Delvers Needed To Collect Those Resources!
A couple decades ago:
Many people awoke in a field on an unfamiliar world. It was obviously a new world, as the world itself arcs across the sky like it is a great ring. Nearby is the base of a great pillar that rises to meet two others rising from the arc of the world in the sky.
In the center of the field is a column with an inscription in the major languages of the awoken people's world.
"Here is the grand test, to reach the top of the pillar. No god shall intervene in this test. You have your own power, your people, and that which you can find in the pillar."
It is soon discovered that other peoples have also arrived, with a similar pillar in their fields, at the base of the pillar.
No tree, indeed no plant larger than a bush can be seen in any direction.
Over the years, many expeditions into the pillar have discovered metal and other resources in the pillar, but none outside it aside from dirt, water, and minor plants.
Metal is scarce and highly valued. Most people live at a primitive level, but life is starting to stabilize as teams bring back resources from the "Dungeon" as it is called.
So now, a great expedition is being formed to go deeper into the dungeon and discover what is there, and brave folks are needed to partake in this venture.
Are brave enough to venture into the Dungeon?
