Castle In The Clouds

A huge floating castle emerges from behind white and pearly clouds. This castle takes the shape that the caster envisions. From the ground, it appears to be full of people. It can be moved by the caster with an action. The castle stays there as long as the caster's concentration does not waver, but it disappears after one day. The caster can send the castle crashing into the ground, dealing 10d10 bludgeoning damage to all who were standing on it. Any who touch this castle will notice that it is corporeal, however, every time the castle is touched by a new person, it becomes slightly more faded. After 1d8 people have touched it, it disappears completely, dropping anything and everything that was on it to the ground. Any materials that were taken from the castle remain in existence for 1d10 days.
