Dherk headed a team of scientists in Atlantis during the Pre-Cataclysmic Age. With his team, he predicted the destruction of their world, but this prediction caused Dherk to be banished to Atlantis' remotest outpost, Pangea, by Atlantis' "enraged ruler"[1] (presumably Kamuu, see notes). There, he began research on a Hybernation Chamber, which he hoped could save all of Atlantis. One such was built on Nahgen Island, another on mainland Pangea. As he was testing the latter, the Great Cataclysm hit the world. Energy backlash from Atlantis' ruined energy plants caused the chamber to malfunction, trapping Dherk within it, but somehow feeding him information, thus causing him to sank into a frozen sleep while witnessing the destruction of Atlantis.[1] Centuries later, the mechanism entered a new phase, Dherk awoke in a half-life state, being able to exist for short periods of time as a mental projection, and even briefly solidify, though needing to return to his sleeping body regularly.[1] One day, Shanna was having delusions due to the effects of the mind-switching device, the Hybernation Chamber. Ka-Zar had been stung and poisoned by a giant scorpion, and Shanna started seeing a ghostly figure, as Dherk introduced to her, revealing her the Atlantean origin of Pangea.[1] Dherk body's was placed in suspended animation. He was able to appear as a projection, but he could temporarily made himself tangible. Dherk first saw Shanna while she was in the mind transfer device and from there he had fallen in loved with her. Shanna did have mutual feeling for the man which was possibly also a result of the machine's influence. Shanna rejected his advances and stubbornly tried to drag Ka-Zar to the Aerians in the hoped of a cure. Dherk appeared later and informed her that they would not arrived on time. He told her he possessed a cure kept near his physical body, but would only share it if she agreed to joined him in his slumber. Out of desperation she agreed, and set out. Due to the distance and freezing mountainous terrain, she passed out from exhaustion. Dherk manifested physically and saved her, and after her pleas for help he reluctantly rescued Ka-Zar. Due to remaining physical too long Dherk eventually died. Dherk's consciousness was eventually revealed to had been transferred into an android duplicate of himself and continued to act as caretaker of the atlantean machines.[citation needed] Whether or not the android Dherk survived the apparent destruction of Pangea remains unrevealed.
