Multiple Scene Game

Hi!
This is a very very dumb question but google doesn't wanna help me....
How can I create a multiple scene game?
See, I'm making an RPG.
I only have two scenes.
One for the library (where you can see the character walking. This is where the events for fights are triggered)
I also have one for fights (Displays heros, monsters, hp, mp, etc)

What I want to do is trigger an event from the library scene and start a fight.
But when I load the fight scene, the library scene still shows up.
If I try to unload the library scene, both scenes don't show up.

I've tried to unload the first scene before loading the second.
I've tried to load the second then unload the first one ...
Nothing seems to work :S

By the way, I'm not looking for script.
I'm using XNA 1 and TorqueX.

Thanks for the help!
