Siren

The Siren, sometimes called just Siren, is the champion fighter in the Crucible. It was mentioned that the Siren often hangs around the Slayer's Take guild. She also serves as a bouncer for the Velvet Cabaret. As an NPC, she is played by Matthew Mercer.

Appearance
The Siren is an extremely built/burly human woman with facial tattoos. When Vox Machina first saw her, she had short hair tied back into a very tight ponytail.

The Siren aggressively beat up a competitor in the Crucible, then wiped the blood from her face and climbed out. Grog was curious to find and fight her, so he asked a barkeep about it. He told him Siren only shows up to the Crucible when she wants to fight. Also, Grog might ask Slayer's Take about Siren because she sometimes works with them. Vox Machina later hunted down the hydra with help from the guild members, who confirmed that Siren indeed had done work with them.

Searching down the rakshasa, part of the Vox Machina came to the Velvet Cabaret, where Siren was working as a bouncer with her dragonborn partner-bouncer.
