Current Status:
Deceased. Killed by Semetra in her Possessed form during our initial encounter.
Species:
Some kind of Lichen[needs spelling check] (possibly wendigo variant?)
Organizational affiliations:
Member of “The Circle of Symbiosis”
Plot relevance:
Encountered within the tree stride portal in the main tree in the garden in the Sanctified District Known within “The Circle of Symbiosis” as their Dullahan summoner.
Seems to be tasked with summoning Dullahan for the purpose of gathering more members for their organization to assimilate in the form of severed heads.
Hints at Cello's master's assailant likely being a member of the same organization.
