But be careful with that. While yes there are portals in PS that do lead to other planes and thus world-workalikes, this should IMO not be used. 1) this is an overused and even more unoriginal / generic way to insert a char into a game without basing it on the games background, and 2) the portals have, for all I can see from the history section, not been passed through for hundreds of years, 3) this sort of thing just generally tastes of bad RP and ignorance of the settings.
At the same note, while letting your creativity roam, try to make sure that it doesn\'t change things in the setting (like inventing new gods, or making existing gods do things, or adding / changing histories of races or events that would be recorded in any major number of Yliaki\'s minds). This means that if you invent a plane to come from, this is not a good idea since it is highly likely to conflict with the plane as it will be implemented later on, invalidating your entire RP.
Also, avoid things that ridicule PS or are out of context in the given setting. While, in theory, time travel or space faring might exist, these things would influence the settings so greatly that they would need to be explicitely mentioned in the settings to be acceptable in PS (apart from being as generic as vampires).
In sommary, you can make up places and people, as long as the places don\'t end up being of importance to Yliakum (like capitals of levels or such, though depending on context that might be acceptable if it\'s just a name and description of a small part of that capital).
Some have created a desert somewhere, which AFAICS is about as far as one can go in inventing places, since there is at least a possibility that a desert may actually exist in Yliakum, even though it is never mentioned int he setting.
In the end: if you are unsure whether or not what you plan is acceptable, don\'t do it.
