Tyranids

Ordo Xenos Kryptman Archive — The Shadow in the Warp & Tiamet Construct

Originating in the cold intergalactic void beyond the Milky Way—drawn toward our galaxy when the overload of the xenos beacon on Mount Pharos (Sotha) during the Horus Heresy flashed like a flare across the dark—the Tyranids are a unified super-organism guided by the 'Hive Mind'. Every weapon, ship, and ammunition beetle is a living creature bred by Norn-Queens inside orbital Hive Ships. When a world falls, capillary towers rise into the stratosphere and proboscis-ships drink the oceans, atmosphere, and digested biomass lakes until only sterile bedrock remains.

Sub-Factions, Secret Orders & Classified Relics

• The Major Hive Fleets — Behemoth (shattered at Macragge in 745.M41), Kraken (broken at Iyanden and Ichar IV), Leviathan (rising from beneath the galactic plane), Kronos (specialized in hunting Chaos Daemons), and Gorgon (hyper-rapid toxin adaptation).
• Hive Fleet Tiamet (The Ziaphoria Anomaly) — The ONLY Tyranid Hive Fleet that does not strip worlds bare; instead, Tiamet defends the jungle world of Ziaphoria to guard a continent-sized psychic brain-tower it is growing out of living flesh.
• The Ymgarl Factor & Catachan Devil — Ancient Tyranid vanguard organisms stranded in our galaxy millennia before Behemoth arrived.
