Sseeth slithered his way into Underhaven few years back skeeking knowlage, knowlage of what? noone but him truly knows. What is know is that for the few years that Sseeth has been here he has provided the Underhaven communitie with significant information about how to best deal with a destroy all sorts of monsters that would threaten the Underhaven. Sseeth has also crafted all sorts of poisons which he tends to sell to those in need for the right price of course.

Word is that Sseeth extensive knowledge on creatures and alchemicals comes from his experiments on other creatures, brutally yet precisely dissecting them thanks to his knowlage of blood magic and performing all sorts of gruesome experiments with alchemicals to aquire the valuable information for both the weaknessess and poisons he makes and provides. These experiments has also proven very usefull in the medical field, giving him expirience to perfor surgeries and patch people up with a simple tools and scarps.
If Sseeth is not brewing poisons, dissecting creatures or medically tending to someone, he is often found slithering from one place to another, observing the current events all while enjoying some raw flesh, for which he has massive appetite, so massive that his serpent tongue flicks out of his mouth to catch the raw scent.

Despite these strange acts, which tend to make many feel a bit uneasy, Sseeth seems to not mind conversation, if anything he seems to welcome when others approach for one, especially if it's about monsters and poisons or medical emergencies in which he might help, very often being welcoming and kind.... in his own way that is.
