Erasmus Greatorix
From Tardis Wiki, the free Doctor Who reference
Erasmus Greatorix was a magician, related in some way to Isaac Greatorex. He used the last remaining pages of the Codex Gigas to summon the Yssgaroth in Chhatak, Bangladesh. The Yssgaroth used a young child, Teddy Bartson, as its conduit because of their stronger in spirit that adults. Azacca Dixon and Agamya Akhtar of PROBE helped Teddy to run away and escape the net of the Yssgaroth's influence. Left with no choice, the Yssgaroth made Greatorix its conduit, and he quickly crumpled under the pressure of its power. (PROSE: The Last Few Pages)
