Magma-forged Armor

Comprehensive study of the unique megafauna on … has revealed transferable thermodynamic insights which can be applied within our shipyards. The mote-infused diet of the creatures results in a heavy silicate-based structure forming throughout their durable outer shells, reinforced with naturally occurring refractory materials. Having recovered numerous samples of their shedded outer layers, our … can now replicate their biomechanical principles in the development of our own hull platings.
