East River Spirit

"The power of Poseidon. He's a jerk, but he sure knows how to sweep pollution away."

- East River

The East River spirit is the spirit of the East River. He dislikes Percy and is a rival of The Hudson River spirit. He is also very polluted.

The Last Olympian
Percy asks him and The Hudson River Spirit to sink all the Titan ships that tries to cross the rivers, in exchange for the Sand dollar his father, Poseidon, gave Percy for his fifteenth birthday. After both spirits quickly agree, Percy splits the sand dollar between them. The East River Spirit calls Poseidon a "jerk" but acknowledges his power to sweep pollution away. Holding their side of the bargain, both river spirits stop the ships from crossing and drown the monsters that try.
