Author's Note: I tweeked the Timeline, so Titans Academy has been open for about three years now. That means it's relatively new, but found a stable way to operate. While Spike arrived in this Dimension, and kid Loki De-aged himself, about a year ago. Conner is about 4 years old now, but still locked in the body of a 16 year old.

CODEXes (as I don't think I ever mentioned it.)

The resident of Midgard and her moons, mature at a human rate, until they hit puberty. Then their aging slows, until they turn the human equivalent of 25. At which point they start aging a year for every 42 years. (trying to explain why kids seem to grow up faster, then adults age, in comics. And how Adults can seemingly live for hundreds of years, without deteriorating.)
