1) A slang term for cocaine.

2) From the game Morrowind: a substance native to southern Elsweyr, harvested from the sugarcane groves of the Tenmar Forest. It is used as a seasoning in foods, a source of communion with the holy moons, a dangerously addictive drug, and an ingredient in another drug called skooma. Considered to be "crystalized moonlight" by the khajiit and regularly used in their cooking. Moon-sugar is invariably sweet and makes even the most bitter foods succulently savory.
