The Wynn
Wynn are purple, soft skinned elf-like people, taller and slimmer than humans, that live on the mountain-tops and tunnels; adepts of elemental magic of primal power their spells come with an unsettling cost.
They inhabit the mountains and peaks to the east, at least until they become too cold and snowy to any survive.
The Wynn access their Fables Deck via deranged creature sacrifices, in which they attach the consumed cards face-down to the summoned Fables to fuel their most powerful effects.
