Brinstone is a particularly hard form of stone with above solid density found on numerous worlds, including but certainly not limited to Tallon IV, Aether/Dark Aether and Bryyo. Since its compact atomic structure makes it strong, it is used as a reliable building material in constructing foundations but rarely on war-torn worlds due to its relative fragility to even the smallest of concussive blasts.
A common way to shatter Brinstone obstacles is to fire a missile, which is the only way known to famous space hunter Samus Aran could figure to move through the obstacles during several missions where she encountered the substance, considering her current weapons complement at those times.
