Rise of an horde

The horizon rippled like waves on a stormy sea, but it wasn't water that stretched endlessly before the city of Al-Kahis—it was horses. A vast, unbroken horde of riders astride their mounts, forty hundred strong, the manes of their horses dancing like dark wings in the arid wind. The sheer mass of them consumed the plains, the grass trampled to dirt, the air thick with the dust churned up by uncountable hooves.

It was a sight the city had never witnessed, and the people on its walls stared in stunned silence, their hearts seized by awe and dread. In their long history the saw their villages rided my some horse lords, yet they never saw such numbers, worse they were not here to simply pillage.

The one leading them after all had named himself Khan of all Khan.
