You plant a seed into a section of ground that has been fertilised by the minerals from each native plane. On casting, the seed rapidly grows into a tree that is 60 feet tall per caster. Once the spell is complete, the tree then connects to each of the planes and a creature that touches the tree can choose to be transported to that plane. Burning a leaf from the tree returns them to the tree, on their native plane.

Once per thousand years a random plane is disconnected. Once all the planes disconnect the tree withers and dies.
