Jack almost laughed... Almost. "Lulu, you have nothing to worry about. I'm over 500 and I'm still here. There are no age limits at this school. They assume most people will leave when they outgrow the place, and generally that's by the equivalent of a 25 year old human, but there are no rules as to when you can leave. Partly because people like me, with very long lifespans, would be kinda out of the running very quickly. At 20 I was still a hatchling." He shrugged.
