Land Mermaid
The name is wrong and everyone who used it knew better. The job board in Vel Rau’dan posted it as a “land mermaid” problem south of Myrrh’s Hollow; Jimmothy pointed out there is no such thing. What was actually holding the Blue Cross Bridge was a siren.
Origin
It was a man once. He lived under the Blue Cross Bridge, and something there turned him. Searching the lair afterward, it was clear the thing had evolved multiple times to reach the state we fought — it did not arrive finished.
The Song
Its song carried far past the bridge. Everyone in the region heard it, and those who failed against it did not recover: The Crazy One was left with madness a history check told us would last years, and he believed the song was why his son killed his daughter.
At the bridge itself the song forced Wisdom saving throws. Every civilian present failed and was charmed into walking off the bridge; the whole party passed. Mid-fight it also charmed Theodore and Roz into attacking each other.
The reach is at least partly explained by its ears. It was wearing The Earrings of Control, one of the 12 Artifacts — “the more powerful the user, the more powerful and vast the control can be.” We cut them off its body.
Lair
It had walled itself into the barricade across the Blue Cross Bridge — 50 feet high, 10 feet deep, opened by a rope like a door. Guards were turning travelers away on both sides, and Myrrh’s Hollow South had been cut off for about a week. Everything inside was covered in slime.

We never saw its numbers. Everything below is a skeleton to fill in — nothing here is from the session.
