Lanka as seen from space. The orange color is due to the fumes that Ravana's factory in Swarga Loka produces.
Lanka is a small planet, with an average radius of around 2000 miles.
Lanka appears orange from space, but this is from the fumes produced by the factories in Swarga Loka. The real color of the planet's surface is a harsh gray. Some of the ground surrounding Swarga Loka has been stained orange because of the fumes, this color is not natural.
Past records suggest the planet was orginally covered in plains.
Most of the organisms that remain on Lanka are either Daemons or mechanical beings.
Lanka used to be inhabited by a sapient race. But Ravana drove them out of their capital city, Swarga Loka, and they were never seen again.
The Praedicans, another sapient race, were driven to near extinction.
