The fleet of Aerymian elves stormed through the bubble zone. These elves from another world did not feel a thing about the defenses of this world. Although they were nervous and highly alert upon departure as it was their first ever real "interstellar combat" mission, they soon found that the enemy's "air force" was not worthy of their attention. Only a few griffin forces and strange flying soldiers tried to intercept them from afar, but those forces were quickly smoked by their fleet and were simply not a threat.
If the Aerymian spacecrafts did not possess warp jump capabilities and had to follow a fixed route through the gateway between the bubble zones, things could have gone a lot easier.
