Dr. Daclaud Heinfroth is the head doctor and warden at the Asylum for the Mentally Disturbed on Dominia. Bogdan Dorgumir also suspects he is the darklord of a Dread Domain, although that has yet to be proven.

What is clear is that Dr. Heinfroth is some manner of “brain-vampire,” a strange vampire that feeds upon victims’ spinal fluid. He no doubt uses his asylum to feed and perform strange experiments on his patients.

Presumably, he still lives on the isle of Dominia.
