Stoysum

Stoysum is a liquid found on Cytens of the Electrono System. It is the primary liquid in it's oceans and can dissolve metals and metalloids which allowed for the evolution of metallic life. When the Gidmuns visited Cytens over time by mistake after a space probe of theirs crashed into the planet after being knocked off course they found out that the liquid could be made to conduct electricity very efficiently and used it in their early technology.
