Don

Don the Faun is a faun that hangs around Camp Jupiter.

The Son of Neptune
When Hazel is showing Percy around camp, Don walks up to Hazel asking for change, like all fauns. Percy wonders why fauns don't help the camp, as he has some memory of satyrs at Camp Half-Blood. However, at this statement, Don just laughs before spotting a diamond on the ground. Hazel picks it up before he can grab it, much to his annoyance, but forgives her as she tells him to "Please go away" instead of just "Go away."

After the battle with the Giant Army, he sneaks into the mess hall and proceeds to ask people for change.

Trivia

 * When Don smells Percy, he can tell that Percy has an Empathy Link with a faun.
