Holiday Classpect concept: a Seer of Void knows what everyone is getting for the holidays by seeing into the wrapped boxes; They give everyone smug looks about it. Everyone learns to hide the Seers gifts in plain sight to prevent them knowing what they're getting at least.
Various Seers could pull something like that off, but what about the Seer of Mind seeing other’s choices and judging who’s been Naughty and who’s been Nice?
