What happened?

Whoa! So... I'm not sure how I got here, and by *here* I mean this body, but I know it... carries some heavy burdens.
Me? Oh I'm just a humble Forest spirit. You know: the one deers feel when they dance, or have fun conjuring, or just lay next to each other. I consume those emotions. And I am so happy they exist. I'm sure the Forest herself is at peace as long as her residents are cheerful and carefree, for she could not have been created so magical and protected from the outer world otherwise. I know she wants her children to be happy, and I'm here to make her will come true. Oh, and yes, to me the Forest feels like a female, as... we were all born in it, don't you think? Anyway it's something on the spiritual level, I don't know how to explain it, and honestly? don't even think it needs to be explained!
So, whatever happened to this body I've been summoned to, must've been horrible. Its original owner must've lost any faith in the Forest. 'Don't want to think what they did to themselves, but... I'm its new master now. I will make sure the balance is restored: for each drop of sadness and despair spilled by this body I will make a whole pond worth of happiness, I swear. I love the Forest and I want her to be at her best.

...

Twin-Gods, I almost forgot! 'Don't know what the old master of this body called it, but you can adress me as Brother Phillip-Theodor the Fey. Or just Brother Phillip. Or Brother Theodor. Or the Fey Brother... Basically just however you want!
