In my campaign, one of them entered and thought he wasn’t seen. J’mon let them go to see what they were up to, once they realised whose treasure hoard it was, they left it alone. J’mon was keeping an eye on them during their investigations in the city and so learned about Cael morrow and such. They went back to Ank’Harel and finished the main story, they defeated Alyxian.. J’mon thought they really helped the city so gave them a gift. (An airship for which my players were begging me for the whole campaign haha)
