You are given a Lunar Exaltation without the Great Curse & without age limits. You have the abilities of a Lunar during starting character creation.
You have Charms & Anima flares similar to a Solar Exalted, but your abilities are more focused on shapeshifting and being mutable like the phases of the moon. You don't quite have the straightforward power of a Solar, but your shapeshifting makes you more versatile. You can gain new shapeshifting forms by ritually consuming the heart of species you wish to learn how to shapeshift into.
Because you probably do not have access to Creation, you gain the Heart's Blood of any animal from Creation your Knacks would have otherwise allowed you to shapeshift into for free, as long as it has no Earth equivalent.
