Lyre of Building

Wondrous item, very rare

Once per week, you can use this item to construct a fortified encampment up to 10,000 square feet. The maximum height of any finished construction within the area is 15 ft. And the maximum depth is 10 ft. The lyre uses materials found at the site including dirt, rocks, and trees. It takes 8 hours for the construction to occur. You must have a rough idea of the final layout of the encampment before issuing the command for it to build, but the lyre will make decisions about what materials to move where. It will attempt to avoid harming any small or larger creatures.
