Destruction of Darcadia

The Destruction of Darcadia is an event that starts upon the world of B'allmar when the Ultramarines were carrying out their mission against a T'au Hunter Cadre when a warp portal materialized within an ocean. On the coast, several Ultramarine Rhinos were gathering in preparation to launch an assault against the T'au. Soon after, they were themselves assault by several Daemon Engines, including Forgefiends, Maulerfiends, and Death Wheels. Within minutes the Ultramarines were decimated, losing nearly all of their Rhinos and attempting to regroup to counterattack. They never stood a chance as Bloody Hands Havocs annihilated them with Kalibrax-pattern autocannons and Mars-pattern heavy bolters.

It soon became apparent that these Chaos Space Marines were once the loyal Ruby Sabres based on surmounting evidence, the main one being that the attack was led by the Master of the Forge Hebediah Briehl, now a twisted Warpsmith. Upon this discovery, the Ultramarines sent three entire companies to the Alpha Lota System. On approach to Darcadia they were fired upon by surface Defense Lasers. Several Thunderhawks are destroyed or shot down to crash land upon the surface of the planet. Only a handful of Ultramarines were able to escape the surface of the planet.

Over the next several solar weeks, the Ultramarines blockaded Darcadia from the Bloody Hands Chaos Fleet. The Bloody Hands continue their piratical raids on nearby Imperial shipping lanes only to be countered by Ultramarines voidcraft. Ultramarines scouts learn that the Bloody Hands had acquired and pilfered gene-seed from fellow Ultramarine Battle-Brothers and have also been ambushing other loyalist Space Marine Chapters to appropriate gene-seed to create more chaos space marines for their ranks.

Upon this unsettling revelation, the Dark Angels come out of warp above the planet of Darcadia. The Ultramarines contact the Dark Angels and relay their appalling news of their vile hosts true intentions. After further discussion, the Dark Angels and Ultramarines come to a consensus that the only course of action may be to use Exterminatus upon Darcadia.

The Ultramarine and Dark Angels assault the planet for a second time. As the traitors fire the defence lasers, the loyalist teleport both their elite 1st companies to decimate the defense batteries to take out all the planet's laser cannons. After the loyalist take out other key targets as the order to destroy the entire planetary biosphere and all life upon the world of Darcadia is given, robbing the Bloody Hands of their price of gene-seed stocks within their former Fortress-Monastery.
