I can t start the adventure "Mountain labyrinth"

[roverw]

Once I started this adventure "Mountain labyrinth" and I guess I have closed/cancel it.
Now I can't start this adventure again.
It is not in my "star list".

This would not be a problem if I could stop/cancel the main quest "When the earth shakes".

Please advice, how to continue.

It would not return if you closed or cancelled it.

You need to obtain "Foot of the mountain" from the Excelsior airship, Run that one to obtain "Unknown Regions" in loot, run Unknown Regions" which will give you Mountain Labyrinth" in it's loot.
