Caelum is a somewhat-Iranian civilization of winged men, available in all three Ages. It may refer to:

• EA Caelum, Eagle Kings ← This one has three clans living in harmony, serving & inspired by ancient angel-like Kings.
• MA Caelum, Reign of the Seraphim ← This one is dominated by a white-winged clan, which rules through its Mages and weapons of Ice.
• LA Caelum, Return of the Raptors ← This one is dominated by a black-winged clan, which rules with steel and Mage-Priests of Death.

All three have Air magic, and flightless alternatives to their main troops that might be more effective.
