When Claw, Gers and Brianne went to their secret hideout they realised that Hellena and her group had been captured by the Shadow Lord. Brianne especially grieved for Hellena, hinting that the two may had been close friends. Hellena was later seen in the Shadow Arena acting as a servant of the Shadow Lord under the influence of a carrier worm in her brain. Hellena and Tira, two of the first perfect conversions, supervised the conversion of the slaves in the Arena. When Lief played the Pirran Pipe, the carrier worm in Hellena's brain crawled out and Hellena was herself again. Hellena, along with the rest of the Deltoran prisoners, was rescued from the Shadowlands. She was ferried through the Pirran Caverns back to Deltora, but due to the magic of the Pirrans remembered nothing of the journey.
Hellena has silver hair and a "strong face". When she was a servant of the Shadow Lord, Hellena wore a long red robe.
