Morphoton

Morphoton was a city located on Marinus.

History
Morphoton was ruled by a group of disembodied brains that enslaved the populace by casting the mental illusion that the city was luxurious, when it was really a place of dirt and squalor. The brains were destroyed by Barbara Wright, thus freeing the inhabitants of Morphoton. (DW: The Keys of Marinus)
