Ooc: Its okay, I understand! I've been waiting for your post the whole time, so take as long as you need! :3
@Lyra ;3 There is an issue with your power. This RP isn't focused around supernatural worlds, there can't be a "mirror world" because you're controlling the mirrors themselves and the light of them. You can use them in an illusional way, as in refracting light in such as way it appears as if you are in multiple mirror, so just so you know. For instance my character Sapphire is just literally hiding within the shadows, she's there, but stretched out to the size of the shadow until she comes back out. Your character CAN use mirrors, or mirror-like surfaces such as metal, to travel, and even broken mirror shards, but not enter a mirror world. It all deals with illusion and refracting light this power.
