I enjoy the play with genre here. As others have pointed out, more proceduralization of the central narrative could help clarify and heighten the stakes. The PCs could contest each other in their struggle to understand the cosmic balance of Law and Chaos. Perhaps a dreamlike PVP meta-duel could be a fun way to both encourage combat of a sort but resolve the situation with a Moorcockian flair. The PCs realize, whatever their philosophies, that they aren't the protagonists in this dimensions and just need to survive/get away. That feels quite Old of School. Points for the runic rifle.
