The experimental results of injecting essentia into a koura parasite once it has a humanoid host. Balhast specifically had a troll host. This creature is quite sturdy though young in its development and behaves more like a domesticated canine than anything else. Though it has high potential for intelligence according to Psionic scans, it is still technically an infant. Balhast specifically is bonded to Vasia in some form, responding quickly to her presence and commands. Others of his designation from similar experiments have shown mild dispositions towards their researchers, though the first one seems to just like Vasia for reasons unknown.
