Siren

Sierra is one of the last three surviving members of the aud tribe, and arguably their leader.

Armadale
Sierra first met Trayen when she summoned him, not specifically, to help her break her brothers out of prison. Rewarding Trayen with an amulet and Teliha with a guide to conjuring magic, she disappeared in a vortex with her brothers.

The Amulets
Sierra and her brothers reunited with the younger members of the UDA during Trayen's quest to track down the amulets aiding him in india by destroying the trifly swarm, in the dungeon of flame by, well just being there, and in the UDA base during the Razing by trying to restore power to the base. But when the power was restored so was the self destruct sequence. After escaping Sierra looked back at the explosion, which destroyed her retinas, permanently blinding her.

Infinity
Despite returning to the group and being made an official agent of the lorecracker tower Sierra still holds a grudge against Trayen and refuses to follow his orders. Sierra has learnt to "see" using her senses of hearing, smell, touch and temperature. Neural remapping has caused her to develop synysthesia allowing her to actually see shapes from this information.

Appearance and Personality
Like all Auds Sierra has pale skin and small pupils. She has black hair and bluish white eyes, her pupils are no longer distinguishable. She always wears a shirt with a musical print.

Powers and Skills
Sierra uses rhythm magic, a subset of magic triggered by song and dance.
