- His name is composed of various words that mean "fire".
- Azar might know Dellingr.
Azar, who was first encountered during Hag Hunt: Heart's Revenge, was a trapped fiery Unknown stuck under the Bathhouse of Aburayan Springs for an unknown but decisively long time. He was used by the Fey for keeping the waters comfortably warm. It's unclear whether his imprisonment was a Fey prank, a show of power, or karmic justice that enslaved a slaver. He couldn't leave the boiler room, since a circle of powerful magic kept him bound to that place and forced him into service.
Sometimes bold (or foolish, or desperate) individuals dared to ask him for wishes.
One of them was Veshta, who used her three wishes to protect her anonymity; to compel the Ledaluscas from the Aburayan primal grove to guard the entrance to her lair; and to Fireball the party that was attacking her. She used the Broken Wish, a Relic of Fire and Water in the shape of a golden seashell, to communicate with him from afar; as a result, his fiery magic clung to the object, producing Ember Dust and granting the Minor Gift of Flare Bolt to the Relic.
The other one was Sauda (though this information is kept away from those who didn't participate on that quest), who wished for the Unknown to be put to sleep; and for the party to be healed; and for the Genie to be liberated.
Azar was unleashed by the end of Hag Hunt: Heart's Revenge, and he took out his brewing fury on the Bathhouse, burning it down alongside anyone who was unfortunate enough to linger inside for too long. The more powerful and brave inhabitants and guests of Aburayan Springs, aided by the party, managed to push against this destruction until he negotiated an exchange with Kakkariel and Sauda, claiming them as his slaves and spiriting them away to Elemental Plane of Fire and the City of Brass, leaving the Millennium Forest behind and ending this threat.
Azar Hacofyre's theme song.
During Save the Slave, four brave adventurers managed to infiltrate Azar's palace on the outskirts of the City of Brass, and liberate Kakkariel and Sauda. Before he could confront them, everyone Recalled, leaving him behind to wallow in his fury. His consequent actions and plans are unknown.
