Avacyn, Hope of Tyria

allow me to be lame and establish a lore for this character:

Knowing the full extent of the dragons power, Grenth sought help from other planes of existence. His old friend Sorin Markov, planeswalker from the plane of Innistrad came to his aid. By way of the Bifrost, Sorin sent his greatest avatar, the Archangel Avacyn to Tyria.

I'm sure some of you will tell me to add highlights, well I am staying faithful to the MTG artwork, so this is what Avacyn looks like.
