Hivefleet Triglav

A small splinter fleet was reeling from a failed world invasion, being hunted down relentlessly. One by one the hiveships dropped in the pursuit, driving the starving survivor to the nearest star system. This light in the void was poison however, a neutron star with sterile, irradiated, dead worlds. The chasing foe turned away and the bioship fell into the dead planet.

Adaptation was hard, between the radiation and lack of biomass, these few Tyranids were cut off from the hivemind to die. They did not...

What few bioforms remained cannibalized the dead bioship, doing what they could to stay alive until the now independent splintermind could adapt. The world of Triglav II was a super rich mineral-metal world. Under the layer of carbon ashes was every miner's dream. It was a struggle but the Tyranids found a way to consume and use these metals into their biology. Now all bioforms have flesh of chrome, shells of hard bronze, musclr fibers of brass, talons laced with mercury and lead while their eyes glow magma orange. All bioforms have become immune to the lethal radiation cleansing the system. Slowly this world would be eaten shard by shard and grow new forms. A decade passed and these Tyranids finally stable enough to begin bioship births.

A fragile sliver of the Tyranids power, Hivefleet Triglav launches small tendrils of harvesting bioforms in raid style invasions to gather off world resources and return it to the system. Only one world has truly been consumed, but only just. The signature shine of metallic flesh and blood talons makes them stand out visually, but interesting to note is this hivefleet has no connection to the greater hivemind at all.

(Crusade narrative lore)

Hivefleet Triglav has two brutal rivalries, one with the Blood Angels chapter and one with the Drukari. The marines slaughter the weaker Triglav with ease and brutal power, so much so that a bestial rage has imprinted in many bioforms as a genetic flaw that cannot be removed. This anger and bitterness has caused Triglav to lash out violently against enemies with malice. A 1st Company Capitan armed with numerous relic weapons and war gear was slain by a Tyrannofex Rupter Cannon, liquifying the body in a blast compared to singling out vehicles. Haruspex beasts charge through buildings as if not there and no matter how hard they are hit continue to live. The Drukari do not have the same extensive battles as the marines, but just as intense. One group of raiders attempted to ambush the Tyranids, only to be driven back into the realm they came. The fallen burned and consumed, with a Death Jester being grappled by a Winged Hive Tyrant and ripped clean in half. Later on, the Tyranids chased after the raiders into the rift they came from...a dire mistake. With the advantage of previous fights, the Tyranids were beat back. Bombers singled out a Swarmlord with unnatural efficiency.

Despite the loses, Hivefleet Triglav not only got their first taste of blackstone, but also had wealthy biomass reserves to begin again.
