The so called "Hateful Wars" were an attempt by the surrounding countries to once and for all clear the various humanoid tribes from the Lortmil Mountains. It started in response to the death of a Prince of Celene at the hands of an Orc ambush. It lasted from CY 498 to CY 510. In the end, it did clear out the Lortmils... but at the expense of overrunning the Pomarj.
The countries involved included:
The Prince of Ulek invited the Barons of the Pomarj to join the wars, but they refused fearing that the Prince would attempt to use this as an excuse to regain control over them.
