Looking for Battle of the Bastards scenario

Hey, about 3 months ago I played Jon and it was similar to Stannis' offer to fight for him, and ravens from the houses came, if they assist or not, and as Jon you had a black COA with a Direwolf, I think.

I thought that this is the Winds of Winter mod, but it isnt there, it's the Stannis' offer and all you have is 800 men.

Where can I find this mod?

Thanks
