I didn't mean it like that; I meant that they get dropped into the action, as in, they make their characters and then it's action from the get-go; there first mission is going to be accompanying a group of other adventurers(most more experienced than then) on a foray into the dungeon halls, and they'll be the only survivors. They'll be from that world, though.
But besides that misunderstanding(my language was unclear, I apologize), what do you think of the ideas so far?
Also, does anybody have any feedback on the massive underground dungeon thing? It's one of several major dungeons I'm including in my world(the others are the Temple of Fire, the Temple of Air, the Temple of Water, the Temple of Wood, Maze of Crystal, Marsh Cave, and probably one or two more that'll be important for quests), and it also doubles as my catchall; i.e., if I don't have an adventure specifically prepared for that week, I can always pull out a bit of dungeon and have an old man or a bridegroom come to the party in tears talking about the dark elves who abducted his daughter or bride.
