*I'm not sure if this is Indian or Celtic myth, but there was a Cyclopean guy who could basically shoot a laser out of his eye. I think it's Indian.
"In Irish mythology, Balor of the Evil Eye was a king of the Fomorians, a race of giants. His father was Buarainech and his wife was Cethlenn. According to legend, he lived on Tory Island.
Balor was notable for his one eye, which could kill anyone it looked upon. He gained this power as a child when watching his father's druids preparing poisonous spells, the fumes of which rose into his eye. His eye was normally kept closed, only to be opened on the battlefield by four men using a handle fitted to his eyelid, or, in some versions, a system of ropes and pulleys."
Reading further into this, it states that it was not Balor's gaze which killed people - he actually shot a fiery beam from his eye. When he died and fell to the earth, his eye burned a big hole in the ground which eventually became a lake.
EDIT: Oooh! Do Cuchulainn in the Warp Spasm!
I have finished a watercolour of warped Cuchulainn - but I can't access my scanner until three o'clock
Yeah that's true, and the sidhe include things like banshees, which are clearly not related to the dwarves.
Really, the only ones from Gaelic mythology that even remotely come close to dwarves are the gaels themselves
ooh yeah I should include Banshees! Probably as a cast of sidhe.. (they should be able to fly, though I'm not sure about giving them a wailing attack or something...)
BIG QUESTION HERE: are there any professions (mechanic, for instance) that might not fit well with the celtic setting?
