Dragon Heist / Dungeon of the Mad Mage

Lliira (pronounced: /ˈlɪərɑː/ LEER-ah) was a chaotic good lesser deity of joy (and for a time an exarch of Sune) in the Faerûnian pantheon.

Everchanging and always lively, she was the embodiment of happiness and freedom, inspiring poets, musicians, and all who reveled in the wonder of a free, cheerful life. The Joybringer was the archetypal ingénue dancer, showing by example that few things should draw one away from the Elysian Rigadoon, a philosophy that prioritized above all things the act of joyful movement.
