Aetherius, or more specifically, Antioch and Khandava:

War with one another when the horde and the athien are not at your
respective doorsteps, as well as at the heels of every other man, woman,
and child in Aetherius.

If you are wise, you will realize that the horde is more of a threat to
you both than you are to one another. Harass one another when you have
ensured that you all still have homes to defend.
