Possibly interested. I was part of a Zelda based RP very similar to this one's idea before--taking place after Ganon's rise to power in the fallen hero timeline--and if I joined this I'd like to use the same character. However, there are a few questions I have related to that:

When Link pulls the Master Sword, Ganon gains access to the Sacred Realm that it was sealing. It's never addressed in the game, but would the Sacred Realm become the Dark World like in A Link to the Past, with the same corrupting properties? Would Ganon use such a portal to bolster his armies, either calling out the creatures of the dark world, or throwing prisoners into the portal and then enslaving their corrupted forms? And would such corruption spread to the Light/Real World through the portal, or would passing through negate the transformation?

Obviously this is all moot if you choose not to have such a mechanic in your story, and that's fine. I just thought I'd ask because the character I was thinking of using is tied to all of that.
