Overview
Thirun is an atraxi disciple of Jorhan in Atraxis Prime. He scouts lands for the atraxi, joins Kheran and Dhalith in a unified barrier during Jorhan's uncontrolled shard eruption, searches Xalmyrra for Arcanis, and later survives the planned purge of Atraxis Prime until Belanor reaches him; Jareth came with the attackers.
History
During the early atraxi settlement in Valrindor, Thirun scouts southern lands rich with essence and life. After Jorhan's shard power erupts on the western island, Thirun joins Kheran and Dhalith in forming a unified magical barrier, and Jorhan then sends the surviving atraxi south to the lands Thirun scouted.
In Atraxis Prime, Thirun continues serving Jorhan as a disciple. He crafts the black-and-violet garments Jorhan gives Eira, and Jorhan sends him and Dhalith to investigate Arcanis after Eira asks about Arcanis. Thirun, Aziran, and Dhalith later search much of Xalmyrra without locating Arcanis.
Death
Thalena arranges the purge of Atraxis Prime by having Jareth bring Isaac's people from Durakarn after Jorhan leaves. The purge kills the resident atraxi except for Jorhan, Eshmir, and Belanor.
Brynor reaches the ruined city through the gate network, with Thirun the only signature he can sense. The attackers came as if they had been waiting for Jorhan to leave, and Jareth was with them. Too badly wounded to recover, Thirun asks Brynor to end him, and Brynor gives him a quick death.
Thirun, Kheran, Aziran, and Dhalith are later counted among Jorhan's slain disciples.
