Zemtrov is the island in the Navius group that is home to many earth elementals and earth genasi, thanks to this better attunement to the ground beneath their feet, plants grow faster on this island. The island is almost overrun with plant life, but the denizens of the island actually use the plants to form their homes, many build underground and some actually reside in tree houses, which is an oddity for people with power over earth itself.
