Nonhuman races in Aerus don’t age as they do in normal D&D lore. All races mature and have lifespans as humans do, with the exception of dragonborne, who reach maturity around 15 and live to be an average of 150, due to their dragon heritage.
These are the current changes to the playable races:
Gnomes – Forest gnomes get the Mold Earth cantrip rather than Minor Illusion. They also learn to speak Gnoll rather than Gnomish.
