This is a very small modification,it was meant for my use but since it is done i didn't see any reason not to make it public.It basically add one faction(House Hightower) which has some renamed units and a couple characters.They hold Oldtown in the beginning,they're built over the vanilla Normans,but I have used only the latest units to stick with the rest of the factions flavor.
Anyway,enjoy it and,if you don't,try to avoid any great complaints,it is a little thing and it was meant to be.

to install it just unzip it in your Med/..mod folder(but first rename the folder in something different than westeros,or it will overwrite your actual 0.53 game.)
