Rudiford was a goody-two-shoes, too good for doing anything like betraying the Kingdom of Falderen, to which he had sworn fealty to (unofficially). Although he was fighting on the wall earlier, he quickly retreated to the keep when he saw the supposed new raid commander gracing the former defense raid commander with a quick and immolating death. Astor Balthas was a scary man, and someone he would rather not deal with, even via chat.
As such, Rudi has been inside the keep since, trying to keep an order of the panicking soldiers and innocent citizens who had nowhere else to do. While he can’t exactly do anything fancy like reinforcing the wall and setting up traps in the hallway, or mounting defensive machineries on the wall, but he sure can encourage the soldiers and assisting with injured people. When he spotted two other players (information revealed to him from extended observation), he came over to them and started chatting them up.
“Hey, are you guys doing okay? It’s going to be a long night tonight.”
