After receiving an Instant Fortress in a campaign I wanted to look and see if there was one here. After not finding one here that is true to size or looks I’ve put together this and tried to stay as close to the in game item as possible.

Inner dimensions are true to the original item, 20X20X30, outer dimensions are bigger due to thickness of the walls.

For those unaware the Daern’s Instant Fortress is a small one inch square of metal that when placed on the ground and the command word spoken expands into a small fortress made of adamantium.

The fortress is a tower, 20 feet on a side and 30 feet high, with arrow slits on all sides and a battlement atop it. Its interior is divided into two floors, with a ladder running along one wall to connect them. The ladder ends at a trapdoor leading to the roof.

This is as close as I can manage to make it to the item. If anybody has any ideas on how to make it closer feel free to get in touch and maybe we can make it better.
