A very rare borate mineral which, in the real world, was discovered in Myanmar in the 1950s. For Warehouse purposes, however, it infuses the entire Warehouse structure, causing any who carry the chemical injected into them, like James MacPherson, to have their blood turn acidic and consume them from within. The only known antidote is the mineral necklace MacPherson wore whilst 'invading' the Warehouse with H.G. Wells.
