"Extinguish" Cantrip

This spell is a reversed form of the light cantrip intended to balance the field for dark dwellers. In most situations the dark dwellers do not need to create darkness, it is already there if they just turn out the lights. With this cantrip a first level sorcerer could be a big nuisance to a dungeon exploring party, who might have to employ two spell casters to have solid light, or resort to using torches etc. Also it establishes a reason to use light spells of a higher level like Daylight.
