Aesir are the gods of Asgard, who can be summoned* and enhanced in the Sanctuary of the Aesir. Their patronage and blessing affect warrior stats and Town development. To build the Sanctuary of the Aesir, your Palace needs to be at least level 18. The Sanctuary of the Aesir cannot be demolished once it is built. Upgrade this building to get access to new Aesir and their power levels.

* Aes summoning here means the temporary activation of an Aes. Not to be confused with Shaman summoning.
