Cortenum
- Mineral including hypersonic elements
- Incredibly dense (SCE Short Story: "Aftermath")
- Used in monocrystalline form for the production of verterium cortenide (ENT Novel: Beneath the Raptor's Wing; VOY: "Investigations")
- Though unable to produce a propulsive field on its own, cortenum's hypersonic properties render it able to channel gravitic energies much as a wave guide (SCE Short Story: "Aftermath")
- Also capable of resonating with subspace effects akin to a subspace coil (SCE Short Story: "Aftermath")
