The hungry dark

Primary Action. Does not provoke. Target 2 by 2 squares. Range 5. Move action+Reaction to sustain, or until the beginning of your next round. An area of utter blackness, but the black itself moves, waiting for a victim. Area must be empty. If someone is in the area (hidden etc) the spell instead goes awry. If anyone enters the area the darkness starts to consume, blinding them and causing 2D6 spectral damage. Swallows all light, no infravision or darkvision. No air- LIF check or suffocate. If a spell is cast in the void and goes awry, the caster disappears never to be seen again.
