Corrupted? Psh, don't even get me started on corruption. Listen to me very closely, I'm centuries older than you are, little pony, if this was corrupted I'd already be an evil crazy creature by now. Buuuut I'm not.

It takes in negative energy and uses it to sustain me, it's not evil. You clearly haven't met a siren in your lifetime.

[She climbs out of the fountain again, shifting back to the four-legged form and prances off just a little distance.]

Not that I expect any of you little ponies to, this place has certainly changed since last I saw it.
