|This page contains spoilers for:||The Strange Demise of Titus Endor (Short Story)|
They both rose to the rank of Interrogators in Hapshant's service, before he contracted deadly Cerebral Worms parasites which began to devour his brain. Though he began to descend into lunacy, Titus and Eisenhorn served loyally under Hapshant until his death when the damage caused by the worms became too much for his body to handle. As Hapshant collapsed and began to spasm, both of his Interrogators were by his side, with Titus trying in vain to wipe away the worms emerging from his mentor's eyes as he died. After Hapshant's death, Titus and Eisenhorn went on to became Inquisitors themselves and began their own careers.
Years later it was discovered that Titus Endor's own deteriorating memory and odd behavior were the result of Cerebral Worms. It is believed that Titus contracted the Worms from Hapshant years earlier, and it was only shortly before his own death from the parasites, that his condition was diagnosed.
