The planet had low surface gravity. This was the homeworld of the humanoid Elaysians and the garlanic tree. Only a handful of Elaysians ever left the homeworld, one of whom was Melora Pazlar. (DS9: "Melora")
Background information Edit
The Pocket TNG novels Gemworld, Book One and Gemworld, Book Two stated that the Elaysian homeworld was Gemworld, a planet considered artificial by some, due to the fact that it should have been extinct long ago, but was kept alive with a "shell" force field and shield setup that also collected different chemicals and substances to convert into energy to feed the Crystal that was now all that was left of their planet. It concluded that, whereas the Frills were native to Gemworld, the planet had been populated with Elaysian, Alpusta, Gendelli, and Yiltern, who were all transplanted from a different dimension by the Lipul, oldest of the planet's inhabitants.
