Magma Exchange Point

The Magma Exchange Points is a point where point where Magma from one planet, system, or star exchanges magma with another planet, system, or star. Rarly, a star's garvity could be naturally altered and a new star would form next to the origanal origin that is connected by a Magma Exchange Point. Their size may vary from 3 decameters to 3 billion kilometers.

Characteristics
The Magma being exchanged would have all the same characteristics of the magma at the mantel of the origin. The magma could be going in one or two directions. Rarely, if the origin's mantel was constructed of dark matter magma, the Magma Exchange Point could exchange the dark matter instead of magma. No cratures could ever live on the magma exchange points except for several species of lava creatures.
