Thanks for the comments. All of which is cool, but nothing in the description looks anything like the Tibetan Empire army of a whole buttload of Cataphracts. So using that army list definitely wouldn't work. This was what I was noticing, although from a much later period. I was reading some 16th C. ...

I am just wondering, what happens to the Tibetan army after 1065AD.

They got invaded by the Mongols in 1240AD and then rebelled again in the beginning of the 14th C, so there is something to game if you were so inclined?
