Although Aeo decreed that deities should not interfere with mortals, it was impossible to completely cut off the influence of deities on the mortal world, otherwise, all the deities who relied on faith would vanish.
Blessings, bestowing Divine Artifacts, or creating avatars within permitted limits to enter the mortal world were all allowed by Aeo.
This Aeolus is almost certainly a messenger sent by the deities.
"But why does he want to marry Airel?" Amberser pondered this question.
The power Aeolus demonstrated was the control of seawater, which didn't seem like self-invented magic, but more like an innate ability.
That said, Aeolus's power must stem from a deity of the Ocean Deity Faction.
If Aeolus truly is an envoy of an ocean deity, then his desire to marry Airel could very well be an attempt by the Ocean Deity Faction to seize more worshippers.
