The typical Shapeshifter lifespan is ~400 years. Certain classes live longer. The rate at which a shapeshifter matures is very similar to that of house cats. The first 5% of their lifetime, IE 20-25 years, they mature at the same rate as a human. For the next 90% of their lifetime they will live as adults. Around 200-250 years (the human equivalent of late 40's) they start showing signs of middle age. 350-375 (the human equivalent of late 50's-early 70's) they appear as senior citizens. The final 5%, from 275-400-ish, they appear as very old, equivalent to a human in their late 70's-90+. Even as they approach end of life they will remain healthy and strong though, thanks to their robust healing powers.
Lucinda is timeless (Lucinda is a Hecate, and they are immortal). She can appear as any age she chooses, but she generally prefers to look like a frail old woman in her eighties. This makes her enemies tend to underestimate her strength and abilities.
Hunter (new character) is fifteen years old. His lifespan is unknown because nobody knows what species he is. The only thing they can be sure of is that he isn't human
