Beau doesn't really have an emotional connection to the Ringmaster or any promise of payoff if they do go save her. But Polaris is pretty big, and full of supplies, and has anybody considered... sticking here and ruling the joint for a bit?

Not forever, that'd get boring. Probably faster than Beau even thinks, she likely wouldn't last more than a few weeks. But rather than go camping in some monster-riddled wylds, they could try pushing the staff into making weapons aand armor and stuff for whatever they do do. Without MoI blocking the magic people from doing magic, this place doesn't seem so bad, right? Just look at all the redecorating they've done.
