EDIT: Beginning of mission two.
The Grand Crusader lamenting on how they could have been defeated sounded quite funny as he was defending in front of the walls, following the best Game of Thrones S8 traditions

.
Minor bug, I think - in the initial "confrontantion" with Balnazzar, our hero had 2 skill points and Earthquake ability available, although he couldn't spend them.
EDIT: Completed mission two. Solid RPG-style first part, than a very climatic final battle, although there were some single lines that felt very unnecessary and out of place, like the dreadlord's "augh it burns", or dreadlord in mission one saying "how could I lose so easily", or something. Like, you're building a very solid desperate and serious atmosphere of crusaders' struggle, then ruining it with these few and minor elements. My advice would be to get rid of these elements to keep the campaign tone more consistent.
I can also repeat my suggestion to reduce a number of troops that join us on our way. Final boss fight was a formality, the only challenge was constant repositioning of my troops so that watchmen and abbots don't get stuck in the rear.
Besides that, pretty cool mission.
