Avandra

Avandra, also known as Lady Luck, the Changebringer, and the Wanderer, is the goddess of luck, change, travel, trade, and freedom. She's a chaotic good deity, who's often prayed to by merchants and other travelers going on a journey, gamblers, and many adventurers. The goddess's avatar often appears as a jovial auburn-haired halfling woman dressed in green.
Halflings in particular often worship Avandra, referring to her as Our Mother. It's commonly accepted that she's the creator of the halfling race. She's also called Thes Ilnnen, which means "unwavering woman" in Draconic, by dragonborn. Although Avandra started as exclusively part of the halfling pantheon, she was adopted into the Eastern Pantheon and is now worshipped by many different races across Eastern Polnarus, including Shan Liang and Shangri-La. The Monastery of Many Colors is an institution devoted to training holy people and worshipping Avandra based in Shangri-La.
