Don't know what to do...

Hello everyone..

When i'm doing that quest of that ghost ritual priest,
he takes me to another place. What do I have to do than?
I have tried to go into the mountain, but somehow I can't
move on. Anyone know what to do?

I made a screen:

Did you do all three missions that you must do? Elona's, Dunes, and Thirsty River? If not, you must complete them before the mountain will open. Talk to all 3 of the ghosts. They'll tell you.

Where can I find those tests?

You have to run through the desert and find them.
