Editing Hive Fleet Nidhoggr (section)

===[[Magma Corer]]===
A distant relative of the Carnifex, Magma Corers have been sighted through many different worlds sieged by various different Hive Fleets; their origin, however, comes from the Nidhoggr. These elusive behemoths rarely emerge on the surface of a planet and so have been hardly studied, the different accounts of their presence usually coming from the effects they have on a planet's lithosphere. Bulking figures, shells hard as diamonds, and sporting enormous shoveling claws, the objective of the Magma Corers is one, to dig deep into a planet's crust as far as they can go and then proceed to detonate in sync to rupture the earth and awaken dormant fault lines. The details of this whole process are still unknown, it is believed the creature secretes an obsidian-like substance than hardens on the sides of the tunnel to keep it from collapsing and that it is outfitted with special synaptic receptors that connect it to the Hive Mind even under tens of kilometers below the surface. Once the desired altitude has been reached, an unknown reaction takes place and the plan is set into motion; in areas where magma is sufficiently basic, the low-viscosity lava will typically erupt releasing huge quantities of dissolved gases, meanwhile, in areas where the lava is acidic and viscous, explosive eruptions and pyroclastic flows have occurred. This results in significant loss of life to all creatures within miles of the occurrence, even other Tyranids, which explains why this type of biomorph is more often employed by the heat-resistant Nidhoggr than any other fleet. In addition, the detonation of Magma Corer from the Nidhoggr Hive Fleet seems to be much more potent in nature, probably due to the different internal biology and conditions.
