I was playing planescape and after finishing the catacombs and went all the way to the upperward. . At the stage of the game, the game provide me with a mini map of sigil and I select wherever i want to go. I decided to go back to the catacombs to see if i missed any quests there.

The thing is that I dumbed all the junk that are used to open the portal inand out of the buried village. So now I cant go back the other parts of sigil, Im stuck in the buried village :(

Anyway to get out of there without using a trainer?

I think you can find some jumk in various containers throughout the buried village, Pharod's kip, and the house behind Ku'u Yin, and perhaps even Marta's abode.

Failing that, you're best bet is to use the Infinity Engine Savegame Editor, to put the teleporter 'junk' back in your inventory.

Try dying :)
You might get teleported back to the morgue

Same thing happened to me. Go to where the teleporter appears and have on of your companions kill you. You'll respawn back at the mortuary.

This is one of the reasons that I love how many extra quickslots you get in PST. I cram all of the potentially useful portal keys into my party members' slots so I don't accidentally dump them or sell them. And because the quickslot items don't get mixed with the rest of your inventory when you pick other items up, it's hard to get rid of them by accident. (Though you can still get rid of them by mistake.)

Of course, death can be pretty convenient, too. Usually if you're stuck in PST, you can get un-stuck by some good old-fashioned suicide.
