This is pretty amazing - YouTube user TerraMantis has put together the story of Crota, the Light Eater, in a seriously beautiful way. It's a tale told with content from Bungie-released videos, self-recorded gameplay, Grimoire cards, and just plain creativity. It's the linear tale as Bungie wrote it, but didn't provide to us. Go watch. Thanks to Blackt1g3r for finding it.
