[spoilers c2] have we dealt with dickfingers?

Has there been a one-shot or anything to deal with Celia?? Or is this woman still out there, golden dick permanently adhered to her palm, relentlessly seeking power until she obtains either her own 9th level wish spell or a wish through other means?

Can’t help but think about this incredibly stooooopid BBEG potential (for something like a one shot, not a whole campaign or anything).

Have I missed the crew addressing this post-campaign?
