Fire Emblem: The Age of Legend
God of Lightning
Minor deity know only because he is attested to as a sidenote in the 1A 1100s or so epic The Forge of Fate as the god of lightning, “shepherd of the storm.”
As Airku is never really again mentioned anywhere, it is presumed that either he is not a very powerful god or that he was slain- probably by Sekeriah. Some heretical sources give him as a son of Ehrholt.
