Arkanenburg

This staff can be lit at will and act like a torch. While attuned to this staff, you can cast the spells Unseen Servant, Create Food and Water and Wall of Stone once a day each.

You can plant the staff in the ground and say its name. The staff then transform into a small outpost made out of a tower with a beacon, a small tavern, stables and a surrounding wall of a 70ft diameter. If the terrain doesn't have the space needed, the staff doesn't transform. The transformation takes 30 minutes.

Arkanenburg has 5 spectral servant with a humanoid appearance of your choice. It is completely furnished and has enough food, water and room for 7 people and their mounts. Arkanenburg remains an outpost as long as you don't change it back, or until you die.
