Iramine

The leader of the Temple of the Iron Mask, she was formerly an adventurer that found an ancient abandoned city with her party decades ago. Her party members and her split what they found in the upper levels of the city (the lower being too dangerous even for the party). They split the amulet key to the city between them, but she has slowly been eliminating the rest of the members to rebuild the key and travel deep into the city so she can gift whatever hides in its depths to Razmir.

She is inscrutable and brutal and doesn't appreciate failure or insubordination. Her mask is rather featureless save for arcane scrawlings hand etched into it roughly. A flurry of other masks fly about her, some matching the herald's masks and during the fight with her she'll summon shades of her former cohorts to fight the players. She is covered in chains.
