[@Double] Then the character I had in mind would probably work, if you approved of it. The idea is something similar to Berserker of Fate/Zero, an enraged knight. In the game, there's one knight we see in the back allies of Castle Town dying from a wound received from Ganondorf. This character is based on something similar; what if, after Link pulls the Master Sword free and Ganon passes through the portal into the Sacred Realm, there is a knight left from the coup d'etat between Ganon's forces and the Hylian army who is still following Ganon, determined not to let him have his way. He fails, of course, as Ganon has already entered the Sacred Realm and taken the Triforce of Power, corrupting the realm into the Dark World. When this Knight enters the portal, he becomes lost in the Dark World, and corrupted by the very rage it pulls out of him. And at the start of the RP, he finally manages to fight his way back into the world of light, with his battered mind only capable of remembering one thing: his quest to destroy Ganon.

Would this work, or does it sound too far fetched for the kind of things you planned to let characters do over the course of the story?
