@Gnome: The original post contains the shortened "Story so far" section to bring you up to speed, more or less. Now for your character.

First, you should expand more on that cocoon. After all, how did Vami alone find it, and where? Finding secrets of the old is a big part of this RP, where does Vami fit in the big picture? Who are the Acolytes of Shadow? Because this make them the 4th secret mage society. What do they know of the others? How do they relate?

As for powers themselves, shape - shifting is OK, but Plane of Shadow does not exist within this universe. While I personally have nothing against such planes, but this would require quite a bit of retcon to implement, so that simply has to go. The abilities can retain their original function, just without any Plane of Shadows things. 

Speak with the Dead, however, needs a big modification. While initially it could work on recently deceased, tearing apart the veil between the world of the living and the dead, dragging out a specific spirit and questioning it is way too much for a starter power. The dead do no remain anchored to the physical world for long, usually.

Change these things first, and I'm sure your character will get accepted. ^^
