Of all the things Ryu had thought Sarriel might have chosen to answer with, this was most definitely the last thing he ha expected.
Ryu had never really considered how to leave this world. How could he even think of doing such a thing until he ripped the Martial Gods out from their roots and slaughtered them to the last man? His only real epiphany about the matter came with relation to the Nether World and he had concluded that if there was anywhere with such an entrance, door or gate, it would likely be that place.
However, never could he have expected that the gateway would be located in the Chaos Plane. Or, maybe, it was just one of the many gateways for all he knew.
