Torg has a number of really cool cosms described in the books: the Cyberpapacy, Aysle, Nippon Tech, Orrorsh, etc. These are rather detailed and are said to each inhabit a certain part of the Earth. In general, the development of these cosms, and the entire Possibility Wars, are developed via metaplot rather than developed with each individual game table.
Because of these strictly defined rules for cosms, I'm wondering: does Torg allow for GMs to create additional cosms in the setting? Obviously a GM can just houserule one in, but I didn't know if there was anything in the official rules designated to allow for this (perhaps some area of the world that was in constant flux i.e. it's whatever you want). If so, are there any rules for doing so?
