[This creature was... different.]

[From Castiels knowledge, sirens were evil mermaids. Upper body of a human, lower body of a fish. But this one.. this one was a bit different. This siren was from a certain Greek mythology. A siren with an upper body of a human, and lower body of a bird. The bird part could vary, so could their wings with its specific species. Castiel was honestly a little disappointed with himself about it, as he was fond with different mythologies around the world. But he'd never had to deal with one on any hunt he'd been on with the Winchesters. Just so happened he stumbled across one looking for a wendigo.]

[It didn't help him that this siren was keeping their distance with Castiel currently, on its knees and low to the ground and injured. Almost making a hissing sound at the angel. Sirens could sing beautifully but sound terrifying when confronted like this. The angel wasn't trying to be scary or hurt the siren though, he wanted to heal them. There was... something about this creature that didn't scream "total danger" to him.]

[To make himself look less threatening, the angel would kneel down, keeping his eyes on the siren. He wasn't even sure if they spoke any english..] "Its alright, I am not here to harm you.."
