Here is a preview of the Darkflame Cleft, a new dungeon in The War Within Expansion, located in the Ringing Deeps.

Darkflame Cleft was once a prosperous earthen mine, but eventually, that prosperity ended. Earthen Machine Speakers moved out, and not long thereafter, kobolds swarmed in. The workers were soon oppressed by a tyrannical Candle King, a tall, bulky brute who towered over his subjects. Obvious wealth was extracted long ago. The real opportunity here is to defeat the last of the king's horrendous henchmen and liberate the intimidated kobolds within.
