The Sea Clan is not the Demon Clan. Their army can only land on the northern coast of Donau, while Lusen City is in the south of Donau, squeezed between Dorott and the Bimon Kingdom. If they anger the Bimon and humans, the Sea Clan army wouldn't be able to rescue them in time — Smey is the arch-nemesis of the Lucian Air Force, and if the Bimon wanted to trouble Lusen, they could do so in an instant!
If the fallen Elves distinguish themselves from the Sea Clan invaders and align themselves with the Aegean Alliance, the only visible benefit for the fallen Elves, should the Aegean achieve a great victory, would be changing the long-standing prejudiced views of the world towards fallen races!
How can one allow others to sleep soundly beside their bed? The fallen Elves know well that a battle between the Bimon and Lucian is inevitable!
The political capital gained now can ease this antagonism and provide the fallen Elves with a larger living space.
