Solid Chlorine

Solid Chlorine is a solid resource obtainable from the Chlorine Planet in the starmap. In practice, it is part of the game’s space exploration rewards rather than a material produced through normal colony processing.

Its presence is tied to that specific planetary source, so acquiring it depends on reaching and harvesting from the Chlorine Planet. No other acquisition method is given in the available sources, so it should be treated as a space-gated material.
