Where to go from Amnoon Oasis

I've got to Amnoon Oasis, but can't find out where to go next?

When I leave the oasis, erverywhere seems to be a dead end. I've find some teleporters but can't get them to work

Any help?

After completing the Sanctum Cay mission:

Here is a link to the quest page on the wiki http://wiki.guildwars.com/wiki/Sands_Of_Souls

And for help in using the teleporters http://wiki.guildwars.com/wiki/Teleporter

There are also maps of the desert area on the wiki page for the Crystal Desert http://wiki.guildwars.com/wiki/Crystal_Desert

I have to say that nowadays, few players explore the desert on their own. They buy a run of the mission points and the three outposts. If you have a few friends though, it can be great fun.

Edit: Some people have obviously had a bad experience in the Crystal Desert, but you shouldn't let that influence you.

And there's damn good reasons for that! The place is a nightmare to navigate, seething with annoying enemies (SCARABS AND DEVOURERS ****ING EVERYWHERE) and they don't even tell you where the missions are (the only missions in the game that are like this, mind you)...

Probably best to hire a runner imo.

Since it's obviously his first time through it, this is a piss-poor idea. Runners should be for people doing these quests and missions for the 3rd or more time. It's never a good idea to get a run through the game your first time. It's only really boring after you already know what's going on.

On the teleporters, stand on the whiteish circle bit then look at the four mini pillars, you'll see a light on the top of them flash in a pattern, just touch the pillars in the same order as they flashed, took me a few tries before I noticed too
