Humbarine III is a very lush planet, though it is very cold. It is the closest planet to the sun in the Humbarine system and has bountiful, cool forests. There are two sizable peninsulas sprouting from the volcanic terrain. An inhabitant could almost survive unprotected on this planet if they only wished to reside on one peninsula or the rocky land mass bordering the volcanic terrain.
Humbarine III has a moderately thick atmosphere that provides a constant cool shading to the ground below. It is unique from all other atmospheres in the galaxy in that it allows heavy amounts of violet light through it causing the ground below to seem purple.
Explorers have found this violet colored light to induce a slight state of intoxication. Medics from other planets in the system also send terminal patients to Humbarine III to help with pain management and, ultimately, lengthen the time they have left. And it has even been known to cure neuro-sensitivities such as migraines due to light and also overactive nerve conditions.
