Kill Team Mercury-Final

This article is an expansion upon existing canon: 1, 2, 3
Kill Team Mercury-Final was a squad composed of former Deathwatch Veterans from the Astartes Chapter of the Prophets of Mercury.
==Backstory==
When the Abyssal Crusade was declared, all of the impacted Chapters had members currently serving in the Deathwatch. These veterans would have to make a choice: to alternatively serve as Blackshields for the rest of their lives- or to end their Deathwatch tour prematurely, and join their Chapter into oblivion.
Several of the Prophets of Mercury- successors of the Marauders, borne of the Cursed Founding- opted for the latter choice, and were given a Nova Class Frigate to command by their brethren. They were subsequently attached to the Ninth Company as a veteran supplement and entered as a thousand-strong force into the warp. Acting as a forward element for the other penitent Chapters, they would be the first to enter the Eye of Terror- and the first to enter the Chaos ambush.
They were never heard from again, save for an encrypted message received almost two millenia later from a derelict ship found to have exited from the Maelstrom. This ship, transmitting the encrypted message on all frequencies, was realized as the Talaria, albeit horribly damaged. This message, when decrypted by Administratum officials, detailed several decades of activity in the Warp alongside the remnants left of the Prophets of Mercury, ending with the message that the Abyssal Crusade had failed- entire Chapters had been seen fallen to Chaos- and that they were the last of the Chapter left alive, sending a message via their ship that they hoped would somehow reach realspace.
The Administratum would block the message's signal while the Inquisition would destroy the Talaria. Most mortals who knew of the message or the ship were either mind-wiped or executed. But the lesson had already been learned by the leaders of the Imperium one thousand years prior when Convak Lann and the Vorpal Swords exited the Warp. Never again would a Crusade be launched into the Eye of Terror.
