The back story of Tomas Alban whom I based on Solomon Kane and started as a rogue/fighter scorcerer went like this
long ago during the Spring Festival his young mother got to be 'May Queen' which is an honoured position in the old pagan fertility rites. As a result she was pursued by the 'Greenman' (also an honoured position) and bumped ugly with him. Well it turns out that that particular greenman was old Farmer Plods' son Jack in a funny suit it was the REAL Green Man, the Leshye, the Erl-King, Llecholan his very self!
ergo Tomas develops Plant powers as he takes on aspects of the Green
Also Orbril the gnome is an alchemist who I have cast as scorcerer a few times inorder to get him the ability to blow things up (which unfortunately DnD Alchemy rules don't much help with) - so I suppose he's a Techno-Scorcerer
