Yeah I think I saw that mission, haven't worked on it yet though. I got a few other random quests going on atm, trying to save up some cash and beef up my new lands further.
Man I really should have started manning up and plowing through those guardians earlier . I didn't realize how much I was restricting myself in the game by ignoring the 4 star missions. It's nice to finally have my kingdom above 30 people heh, plus I got some sick buffs for my soldiers and just got the harden soldiers.. The sky's the limit now!
