Cause of Return

The turmoil had finally subsided as the battle concluded on the peninsula shaped by the God of Life. The triumphant party emerged as the Hero of Life's group, consisting largely of Kahn's own subordinates.

When Kahn initially entered Hesperides in the guise of Atreus, a member of the Hero of Nature's party, he was taken aback by an unexpected revelation. His innate connection with his subordinates allowed him to sense their presence. Ronin, in particular, reached out to him through their mental link, explaining the circumstances that led them to become part of the Hero of Life's party.

The main reason why they were here in the first place was because Kahn himself sent them here.

Technically, not the real Kahn but the doppelganger he left in the Zivot Empire aka the Elven Empire as Legolas Ragnarsson.

And the reason behind his action was due to the Hero of Life's party being allegedly annihilated by the infamous Hero of Darkness.
