So back in 2019, in the early part of my campaign, there was an unresolved storyline that the party never followed. It was to do with abberations and eldritch creatures. They encountered a number of 'humanoid larval creatures' that they were unable to identify, and never followed up on. This was originally intended to become a sort of side-story campaign called "Mask of the Betrayer".
This campaign was to primarily follow Harken's journey, and would tell more of Dichys' story. Who he was and where he came from, and helping to heal his condition. The story was that the god Mask, god of deception, had in fact been killed and replaced by an obryth (a sort of proto demon), and the only ones who knew about it was the cult of Demogorgon.
This character here, Theta, was the secondary villain. He worked on the side of "Mask" and represented one half of the influences of Dichys, with the other half being Demogorgon.
Anyway, because this campaign never happened, I never really got to flesh a lot of these characters out. But now I am somewhat tweaking Theta by adopting another character to make him more whole.
He's mine, he belongs to me now.
