Going to be interesting if they stick to the canon age tables.
Are there any canon age tables though? Even with humans I am not sure.
Mages could deffinetly be interesting. They tend to live longer than their brethren. It would be super cool if mage class characters could have a prolonged life due to their arcane abilities.
As Aegwyn was almost 900 years when she died (Guardian trait OP) and Antonidas was around 100 years old during the First War, it would make sense.
