Tachran was a small planet in the Outer Rim, home to the Tachrani people. It had very little light, and most of the native plants had evolved to create food through a combination of thermosynthesis and photosynthesis, as there was not enough sunlight for them to make sugars through photosynthesis alone, even though the plants could make 10 times the amount of sugar through photosynthesis that plants on brighter worlds could.
