Silicon/Legends

Silicon was one of many elements in the Galaxy. It formed with oxygen to make silica.

It was the base element for vacuum-breathing species like the space slugs and mynocks and the mineral lifeform rainbow gems and Shards. The Silika people of Dohu VII were also composed of silicon.

Behind the scenes
Silicon presents similar chemical properties to Carbon and some experiments of creating silicon-based organic compositions have been made.

The possibility of existing (extraterrestrial or not) life-forms has been ventured both in theory and science fiction. In reality, silicon-based life is unlikely. See the Wikipedia article for Alternative biochemistry.
