Heroes of the North
Only hinted at by the Underthing that plagued the Deep Folk of the Earth Manse, The Devourer is a being of untold power locked away in the northwest. If free, it would be a power capable of taking on the majority of the Wizard’s forces all by itself.
One would have to be very careful working with the Devourer, finding a way to free it under very, very specific conditions. The consequences to Creation otherwise could be terrible.
