If I do not remember wrong hes from Greece and was at least doing commission painting in the past. http://www.lustria-online.com/threads/comissions.7449/ The slann looks to be a limited games day model of the slann that has had some conversion done to it.
Not sure who he is, but the completed pictures are on pinterest Also golden demon winner. Spoiler: Mazdamundi
