They were created with Mondain's Legacy, I did the math on it awhile ago and mine that is currently 579 weeks was created the very first week they were available. So unless someone happens to have one from the very first minute they were created or something, you're right that 579 is the oldest they can be currently.Two at 579 weeks old here as well, I'm guessing that's as old as they get. Does anyone know when they were first introduced into the game for sure? Also, they don't age in deed form so keep them on the perch!
