[@Emma] Fae are essentially immortal if they do not fall ill or are killed. Aging depends on the Fae. Falk (The Fall King) is ancient even among the Fae and he rivals Runlauf in his years. Falk looks young, fit. Like a late 20's, early 30's man. Another Fae could look like a child or a old man depending on their own make up, namely power. They only die of 'old age' if they will it, or their power wans enough.

Season Born are generally used as servants as they are being turned. But they can rise high in the Fae Courts like any other Fae. Yes they are Changelings.

And Yes they can change Court, but beware of the retributions for it. Ie being hunted down, killed, enslaved, and if you make it without that being watched forevermore.
