The Underhalls of Frostwound

A barren, white land at the end of the world, and there, the Citadel. 
Gleaming spires of ice rising to a clear sky, thawed and frosted again.
High balconies and pillars eroded as limestone, featureless.
And among the lonely streets and halls, they eat, love and die.

Frostlanders.

Their numbers are few, their chances even less.
‘Cause from the depth of dreams a call has been made,
to trail the Underhalls for its secrets to confess.
