One of the more successful invasions of Agbithan Gafhi, the flood of dragonthralls from the mountains reached the river Baratre and besieged Harhoun, but were ultimately beaten in the April of 498 by Yaner's forces. In the following months, the dragonthralls were pushed out of crusader land.
In the winter of 504, the Pillar of Horns sent forth marauders into the whole of the Baratre valley. Though the invasion swept away resistance in the far east, the Howudra Gafhi bled the dragonthralls in the north as the Gafhi Serafi reformed. As the dragon's forces overextended themselves, the Gafhi Serafi led by Yaner smashed them at Koskaro on the 12th of May. In the following weeks, the greater proportion of them were driven away from crusader land.
