Hi there, check out the spinoff of Second Universe in Ashes In The Wind.

In this story Symbol has been resurrected and is being taught how to become a displacer by Roden. He, along with the symbiote pony Abi, must now displace someone.

However, the one they displace does not let Symbol leave, so now he must join Portgas.D.Ashley while they track down the Nightmare that was once trapped in Symbols body.
