Appearance: Solli is almost typical of his species. Tiny, grey skinned, hairless and sullen. His most obvious trait that sets him apart from the rest of his brethren is the awful scarring that cover his face, neck and head - received from a particularly viscious cave in whilst in party hunting a Mind Flayer in the deep depths of the Underdark. These scars make him all too ugly to look upon without turning away and that is before one can notice his natural scowl. His armour and pack are wholley functional, the snakeskin of his armour even filed down so as to be extra dull and "un-noticable". He always has his Dart Thruster in his hands, even as he sleeps, a leather thong attatching it to his right wrist.
Background: After Blingdenstone (s/p?) was destroyed by the Drow, Solli and the remainder of his family did not go with the others of his city to the haven the surface dwellers offered to provide. Instead, they struck out with a small number of friends and retainers to a sheltered area where they tried to create their own settlement. Unfortunately, this was also destroyed, a viscious raid by an Illithid attack. Solli and his younger cousin were sole survivors. Ever since then Solli has felt he has had no home, no commitments to anyone but him self. Well, except for Rogoth, a typically blind Grimlock that managed to latch onto the small man and aide him (And he aide in return) with his muscle and natural ability to hunt in the underdark. Together they have spent many a time hunting evil, for Solli they team up to slay Mind Flayers and their minions - Rogoth always seemed to have a grudge against the Drow, though Solli was more than afraid of them.....
