Today a thought struck me about how there are many tales of ships that are lost at sea. The general assumption is that monsters, pirates, or a storm took the ship out. That is good for most games.
But what if there is a phenomena that a storm at sea could instead open up a gate to another world? "We got lost at sea, and we have no clue where we are... in fact, the stars look different. I think that we are on a different world altogether".
That could be a handy way for a Game Master to transplant his PCs into another world. But take it a step further, and it could be a way to deliberately travel to other worlds. But how would this be done? Control Weather could technically do it, especially if creating a gate is defined as a "natural" occurrence (which would account for the accidental travel).
This sort of situation would add a bit more to the sea-faring side of a campaign world, or at least for a group of PCs that want to explore (and loot) other worlds.
Do you have any ideas and/or suggestions regarding this train of thought?
