Aquilon-Terminators Lastrum Storm Bolters

A trio of Legio Custodes Aquilon Terminators wielding Lastrum Storm Bolters.

A Lastrum Storm Bolter is a unique pattern of Bolt Weapon utilised exclusively by the Legio Custodes, the elite bodyguard of the Emperor of Mankind. The Lastrum Storm Bolter was named for the weaponsmiths of the Lastrum Core Clan of the Appolyne workshops of Terra.

Other than being exemplars of their kind in terms of skill of fabrication, they would not be remarkable save for their uniquely powerful ammunition. Rather than the usual "Kraken" type bolts utilised by the wider sweep of the Legio Custodes, the artisans of the Lastrum clans hand-manufacture only customised mass-reactive heliothermic warheads for their bolt shells.

Once within their target, these burst into brief, but sun-hot incendiary detonations, incinerating their victims from within. These shells are uncommonly dense, requiring a far stronger charge to launch than common bolt shells, and only the Lastrum's uniquely sturdy construction for a weapon of their size can withstand the stresses of this repeated firing.

During the Great Crusade era of the late 30th Millennium, the sheer resources and skill required to craft these weapons were immense, and they could never have hoped to be mass-produced to arm the Space Marine Legions. Even the output of entire generations of the Lastrum Clan themselves could barely satisfy the demands of only the Legio Custodes.

Lastrum Bolt Cannon

The Lastrum Bolt Cannon is a heavier, more potent version of the Lastrum Storm Bolter that is mounted upon the forward hulls of the Custodes' Gyrfalcon Jetbike, Coronus Grav-Carrier and Caladius Grav-Tank.
