I'll start with
Name - Demos Fannell
Chapter - Blood Templars
Rank in Chapter - First Captain, Blood Guard
Personal Quirks - Demos has a curt temperament he has shown open scorn and distaste for the Inquisitorial overseers and those who disrupt his quiet reserve the only individual he seemingly tolerates is the Chapter Serf he brought with him when he rejoined the Deathwatch for his current tour
Armament - Equipped with a master crafted bolt pistol, powerfist, and .998 Godwyn pattern Bolter with extended magazine
Any Deeds of Note - Captain Demos has served no less that fifteen tours with the Deathwatch somewhat a veteran and man of myth he is a fearless warrior leading daring raids against enemy numbers that greatly exceed his own forces, most noted of his Deathwatch deeds is the purging of the Agriworld Salieth which defected to the Tau empire, his task force met heavy resistance against a well dug in force yet under Demos' careful planning their command cadre allowed themselves to be ambushed and wiped out, lost of their command the Tau forces were cleansed by Imperial Guard reserves under Demos command.
The Blood Templars
Combat Doctrine - The Blood Templars are above anything hunters, predators trained in harsh conditions against prey that is easily a match for their predatory nature, a blood templar is a master stalker driving and luring their pray into a perfect ambush where they are utterly crushed in a single bloody and violent action carried out by methodical killers, for behind their calm exterior resolve lies a cunning master of death.
Organisation - The Blood Templars do not follow Standard Codex practices their chapter is divided into Six Clans of varying numbers as each Clan recruits and trains it's own scout units meaning that one clan can be larger than the next, each Clan is commanded by a Clan Master (or Blood Father) who acts as a Lord of the Chapter second only too the Grand Master (The Blood King) Each Clan Brother lives and grows in his Clan all schools of combat are nurtured within the clan but they each aspire to move beyond the Clan's into the ranks of the Blood Guard the elite of the chapter and the Grand Masters Personal Guard, each one of the Blood Guard is a hero of legend within the chapter and they stand aside from the rest of the chapter organisation given freedom to come and go as they please within the Clans seconding themselves to actions as they see fit, of all the marines only the Grand Master has the right command them as a single force. It is common for the Blood Guard to leave the chapter and Join external forces such as the Deathwatch and many take the watch several times in their lifetime to better hone their skills of warfare.
Beliefs and Practices - The Blood Templars follow the ritual of Blooding prior to any conflict in which they spill their blood slaking the worlds thrist for it and pledging that no more of their blood shall be spilled in the battle to come, they also share the blood of their brothers in a ritual called The Bonding, at the same time as the Blooding the marine will add his blood to a chalice passed round mixing his blood with that of his brothers, once this is one they all drink of the cup sharing in the combine mix, in this way they ensure that should they fall during battle their spirits live on in their brothers and their strength will be with them in the battle.
Notable Traits - The Blood Tempars have prominent fangs giving them a vampiric appearance but unlike their Blood Angle cousins they do not thirst for blood instead they are the cunning predators that stalk the dark places, the eyes of some marines have been reported to change to a burning red in the thick of battle.
Relations with other Chapters - The Blood Templars have a good relationship with the Crimson Fists for they share a common trait with one another, both Chapters have been brought to the brink of ruin and survived the Blood Templars are a shattered Chapter only a few strong yet their resolve to rebuild is something the Crimson Fists can relate too, The Chapter has also had violent run ins with the Nigh[EXCOMMUNICATE]ch and Mentors Chapters with open threats of hostility towards both being issued, their current Grand Master has also come to Blows with commanders of the Ultramarines and Salamanders leading to some tensions existing regarding slurred honour.
There we go your Captain
