Veins of Crystal and Blood
Prontera, and Bennal, met its end in the Incursion War, when the Githyanki drew the majority of Bennal’s army into a conflict against Geryt on the plains a few days northeast. While Bennal’s army marched northeast, a massive portal to the astral plane opened just outside of Prontera, and the city was easily taken. Once the city was razed, the Gith moved northeast to finish off the Bennalish army in a pincer attack with the forces that had lured them out there to begin with. In a matter of days, what was in the 3rd age the most powerful military nation had been reduced to smoking rubble.
