'''Ols''' are shapeshifting creatures that can take the form of almost anything. They were created by the [[Shadow Lord]].<ref name="tDBoM">{{Cite|The Deltora Book of Monsters}}</ref>

== History ==
At some point in the past the Shadow Lord decided to create the Ols in its [[Shadowlands (location)|Shadowlands]] [[Factory]].

=== ''The Deltora Book of Monsters'' ===
[[Josef]] was hunted by two Ols disguised as fruit sellers after he spoke to a [[Sha-Ban|Dread Gnome]] about [[Gellick]]. They tracked him down to the sewers where he lived with [[Ranesh]], but were killed by Steven and Nevets, who had been following the Ols in turn.<ref name="tDBoM" />

=== ''Maze of the Beast'' ===
[[Lief]], [[Barda]] and [[Jasmine]] encountered two Ols near the [[River Tor]]. The Ols had been following the companions and eventually took the shape of two girls named [[Marie]] and [[Ida]]. Initially the companions fell for their trap but [[Dain]] was there to rescue them.

While travelling with Dain, Lief and Barda saw two water birds and they tried to feed them. The birds were not interested in the food and eventually spread their wings. It was then that Lief noticed the mark of the Shadow Lord and knew that they were Ols.

On the ''[[River Queen]]'', Lief, Barda and Dain met several passengers. One of the passengers was a lady in a Pink dress. She was on the boat with her partner. When the pirates attacked the boat Jasmine lost her disguise and the lady in pink recognised her. She changed to her true shape - the shape of an Ol - and proceeded to attack Jasmine. The Ol was eventually killed by the [[captain of the River Queen|captain of the ''River Queen'']] before it could kill Jasmine.

Barda had been knocked off the ''River Queen'' during the pirate attack. Jasmine and Lief thought Barda had drowned and despaired because they had lost almost everything including the [[Belt of Deltora|belt]]. Then suddenly Barda appeared and the companions continued to search for the pirates who had the belt although the pirates were not aware of this. Eventually the companions wandered into a cave and found a note. The note had been signed by doom and was written for the pirates. Lief and Jasmine realised that [[Doom]] had betrayed them and that there was little hope of getting the belt back and obtaining the gem from the Maze of the Beast. Barda urged them to give up and go home. At that moment the real Barda appeared and killed the other Barda who was in fact an Ol all along since he had joined them again after the pirate attack.

Initially this Ol had the shape of the man who accompanied the pink lady on the ''River Queen''. They were both Ols and travelled together, just like Ols normally do (grade 1 and grade 2 Ols). The Ol that had the shape of the man on the ''River Queen'' and later the shape of Barda, had held the shape of a white water bird that Lief recognised as well. This bird was similar to the water birds that Lief, Barda and Dain encountered, the water birds that were also Ols. It is unclear whether the Ols on the ''River Queen'' are the same as the water birds that the companions encountered earlier.<ref name="tMotB">{{Cite|The Maze of the Beast}}</ref>

=== ''Valley of the Lost'' ===
Lief, Barda, and Jasmine encountered a group of Ols disguised as goats guarding the [[King's Bridge]]. The companions watched them go through the Tremor before continuing along the road.

Near the city of [[Tora (city)|Tora]] the companions encountered Doom and [[Neridah]] and suspected that they were Ols for a moment. This is however proven false when they both walked through the magic tunnel of the city. If they were Ols the magic of Tora would have killed them.<ref name="TVTL">{{Cite|The Valley of the Lost}}</ref>

=== ''Return to Del'' ===
Lief used the water of the [[Dreaming Spring]] to spy on Fallow. He realised that Fallow must be an Ol because of the words Fallow had said to his father during an earlier dream, and that he was likely a Grade 3 Ol, the kind Dain had mentioned rumors of that could imitate humans in every conceivable way and even take on the form of non-living things.

During the journey to Del, Lief, Barda and Jasmine hid in Steven's wagon. Steven informed the companions that they passed by many Ols. All the Ols were however not interested in Steven and his caravan.

The companions and the [[Resistance]] embarked on a rescue mission to save Dain after he was supposedly taken by [[Ichabod]]. They all believed that Dain was the heir to the throne and that only he could wield the belt. Lief wore Dain's dagger during the journey to Del but in the palace he realised that he had lost it somewhere. When Lief cut the ropes that bound Dain, he saw that a trap had been prepared for Steven and Nevets. Several rats changed to their true form - the shape of an Ol- and attacked Steven. It was then that he also saw the dagger on Dain's belt and realised that Dain had been a traitor all along. A grade 3 Ol created to deceive everyone and serve as a false heir. Dain lashed out at Lief and knocked the belt into a nearby fire. While Lief talked to Dain about his role, Doom tried to attack him from behind. However, Doom was unable to defeat Dain because of his speed and shapeshifting abilities. Doom's attack bought Lief enough time to recover the belt from the fire and clasp it around Dain's waist, killing him.

After Dain had been killed by Lief, the Ols at the palace were stunned for a moment. The companions including Doom used that moment to flee the palace and plan their next move. They went to the forge but eventually the guards came and they captured Barda, Jasmine and Doom. Lief hid in his room until the guards left. Meanwhile the captives were taken to the [[Place of Punishment]] in front of the [[palace of Del]], to be executed publicly, along with many other [[Resistance]] members. Fallow was to carry out the task and addressed the crowd of Del calling the Resistance fighers "traitors." Before the executions could take place, however, Lief, who had been arrived but was in hiding, appeared at the Place of Punishment. In the following chaos of Lief's final effort to try and reveal the heir of Deltora, the grade 3 Ol Fallow was killed by having the burning, liquid light contained in one of the red cone lights on the platform of the Place of Punishment, poured all over his body when he had grasped at it and accidentally tipped it towards himself.

When finally the Shadow Lord's power was undone in Deltora, with his departure and by extension the withdrawal of the Ols' source of power, the remaining Ols in Deltora had died, collapsing with burst and shrivelled hearts.<ref name="RtD">{{Cite|Return to Del}}</ref> Some survived, but were forced to remain in the Shadowlands.

=== ''The Shadowlands'' ===
After the Shadow Lord was banished back to the [[Shadowlands]], it decided to replace the Ols with the [[Conversion Project]], since Ols had proven too prone to human weakness. The last Grade 3 Ol created was [[3-19]]. [[Lief|King Lief]], [[Barda|Captain Barda]] and [[Jasmine]] spotted 3-19 in the Shadow Factory. In the Shadow Arena Lief saw several Ols entertaining themselves by changing shape. 3-19 was killed at last when he hesitated to start the conversion project.<ref name="TS">{{Cite|The Shadowlands}}</ref>

== Habitat ==
Ols roam Deltora and more specifically the west of Deltora, especially around the [[River Tor]]. The Shadow Lord sent Ols to Deltora to do his tasks.<ref name="tMotB">{{Cite|The Maze of the Beast}}</ref> After the Belt of Deltora was restored, its magic turned the Ols in Deltora to dust.<ref name="RtD" /> Some Ols survived, but were forced to remain in the Shadowlands. Ols appeared in the Shadow Arena, serving as audience during the fights.<ref name="TS" />

== Anatomy ==
An Ol's real form resembles ghastly, flickering white flames, as well as smoke, or a boiling raising mass. They have holes for eyes (which sometimes is described as glowing red) a toothless mouth. A spike resembling a scary big flame rises from their head. They have very long arms with strong hands which they often use to strangle their victims. In this form they have the mark of the Shadow Lord at their core.

Whatever shape an Ol takes the mark can always be found somewhere on its body, though it can be in different sizes. In Marie and Ida's case it was a little mark on their chin. Ols always try to hide the mark with clothes or along with normal marks, such as tattoos. To defeat an Ol, one must pierce their heart, placed on the right side as opposed to the left. When they die, they melt into a mass of white and parts of the things and peoples they have taken form of is being revealed in the white mess.<ref name="tDBoM" />

== Behaviour ==
=== Grade 1 ===
Can take the shape of living people they have seen, but are very cold, cannot eat or drink, have the mark of the Shadow Lord easy to see, and must take a break from the shape every three days. When they take a break they falter and shimmer. This is called "the Tremor". They always travel in pairs.<ref name="tMotB" />

=== Grade 2 ===
Cunning and difficult to recognise. They can successfully pretend to eat and drink, make their skin feel warm, hide the mark very well, and can travel on their own. They do however, still suffer from the Tremor every three days. <ref name="tMotB" />

=== Grade 3 ===
Grade 3 Ols can take the shape of non-living things as well as living creatures and are able hold the disguise indefinitely. They are extremely difficult to recognise, as they are almost always warm, eat and drink, do not change shape often, and hide the mark almost at an unrecognisable state. However, this perfection comes at the cost of vulnerability, as a grade 3 Ol in the shape of a human can still die as a normal human would.<ref name="tMotB" /><ref name="RtD" />

=== The Tremor ===
The Tremor is the process that Ols go through when they hold a shape for three days. The Ol's control over their shape weakens, and they momentarily return to their true form. The process is very quick, but usually all the time needed to figure out what the Ol is.<ref name="tDBoM" /><ref name="tMotB" /> Grade 1 and 2 Ols experience the Tremor, but grade 3 Ols are able to hold their shapes indefinitely.<ref name="tDBoM" />

== Diet ==
Ols have no need or desire to eat, regardless of any form or transformation they are in. They can, however, pretend to eat.<ref name="tDBoM" />

== Anime (non-canon) ==
[[File:Merging Ols Final Form.png|thumb]]  

The role of Ols in the anime is generally the same as in the books. However, Dain and Fallow do have extended screen time and an elaborated plot in comparison with the books. Their roles are expanded after the Shadow Lord's defeat in Deltora, as even after their master had vanished, many Ols  were still able to operate within Deltora, prompting Lief, Jasmine and Barda to go on another adventure to seek the source of the Ols in the land. It was later discovered by the heroes that the Ols were receiving dark energy from a source buried by the Shadow Lord. It laid hidden beneath a giant Ol disguised as a mansion. Zeean used her magic to dispel the evil which finally rid the land of the last of the Shadow Lord's servants from Deltora.  
[[File:Merging Ols Transform.png|thumb]]

=== Merging (non-canon) ===
Special low level ols with the ability to merge. The final form is stronger and larger depending on the number of Ols merged. Because of its height, its weakness point is harder to reach. Also, they can separate if more numbers are to the Ols' advantage.

=== Known anime-only Ols (non-canon) ===
*[[The Seer]]
*The Foursome (Barda, Jasmine, Filli, Kree)
*[[The Disguised Ol]] (Mansion Ol)
