Unless we give him the force he'd probably lose a hand, and as a wizard he really wants to avoid melee anyway.
They exist, but I don't think they were ever explicitly made accessible via the nevernever. The instances are sandboxed basically, you need to be something like an Angel to cross the borders.
Honestly I'm more interested in the "small scale" stuff.
Full adventures in our hell would take a lot of screen time, but if the first three levels of prayer eating have an advantageous interaction with our hell we could get something a lot less IC and OOC time consuming that still lets us interact with it.
Specifically by advantageous interaction I mean the range limit falling off because the people praying are technically inside Molly's soul, and the weirdness for the visual check with no range that works across dimensions getting a similar flexible interpretation that lets us peak at worshippers in the same circumstance.
Then we could have Molly spend a few hours a week meditating to answer prayers, and background most of them with the exception of little flavor snippets that show snapshots of the life and trials of various people in the FFCF as we help them via fate manipulation.
