Cinder
Cinder Forge is a cinder biome that runs up to Threat 25, and everything in it is Fire — so Burn and the Ignite payoff are the language of the fight. Cinder Wyrm waits at the end, with 900 health and 8 Uniques to give up.
A run through it lays out 26 rooms — 1 entry, 16 combat, 1 boss, 2 transit, 1 shrine, 3 branch, 1 loop and 1 placeholder — and draws 0–10 of the combat ones on any given floor. Come in around level 4.17 for every Threat step you are attempting, with about 10 power for each of your levels.
2 creatures from the shared Demon crowd are swapped out here: Imp → Cinder Whelp and Imp Overlord → Cinder Wyrm.
