A Grey Knights Chaplain is a specialist officer of the Grey Knights Space Marine Chapter and like his counterparts that serve other Codex Astartes-compliant Chapters, serves as the appointed spiritual leader of the Chapter. Chaplains are the warrior-priests that minister to the spiritual well-being of their fellow Battle-Brothers, instilling in them the values and beliefs of the Chapter and promote the veneration or in rarer cases the actual worship of the Emperor of Mankind. Chaplains lead from the front as awe-inspiring warrior-priests, fighting wherever the foe is most fierce, leading his brethren and praising the Emperor through the destruction of His enemies. Rejoicing in the glorious act of war, Chaplains exhort their Battle-Brothers to ever greater deeds of bravery and devotion.
Grey Knights Chaplains act in a similar role to those of other Chapters by serving as the spiritual leaders of his fellow Battle-Brothers. However, the challenges facing a Grey Knights Chaplain are unique. The rigours of serving in the Grey Knights can sometimes be daunting, for the life of a Grey Knight is one of sacrifice and duty as they face the worst horrors of the Warp. They will never know peace or respite for their war is an eternal one, fighting against the vile Daemons of Chaos. Over many centuries of facing such malefic creatures, a Battle-Brother will lose many comrades, should he live long enough to survive the countless trials and struggles against his daemonic foes. Even the nigh incorruptible Grey Knight warrior can have his faith sorely tested; overcome by nearly overwhelming sadness and impotent rage at the loss of a close comrade or commander. To be a Space Marine required an extraordinary man, but to be a Chaplain required more. A Chaplain of the Grey Knights was a rare specimen indeed, and the Chapter had precious few. A Grey Knights Chaplain had to minister to the spiritual needs of soldiers destined to fight the most horrible of foes. The men of their flock constantly looked upon the Warp and heard the whispers of daemons, and yet, thanks to the Grey Knights Chaplain and those who had preceded him, not one Grey Knight had ever become corrupted by the enemy. But sometimes there was doubt, especially in regards to the futility in the Inquistion's task of defeating Chaos.
A Grey Knight never doubted the righteousness of their cause, for fighting the daemon was not a gesture of futility. They believed that is was a true and righteous purpose, for they had seen the results of the daemon's depravity. But their fight was only half the battle, for the daemon was but one manifestation of the Archenemy and its violence was but one weapon of the Warp. The Inquisition battled the plans of Chaos just as the Grey Knights battled its soldiers. But sometimes, even one of their number could fall to pernicious will of the Ruinous Powers. Over the millennia, many Inquisitors had been lost to the temptations of Chaos, though a Grey Knight knew they should not speak of such things. Sometimes there were rogues that hid themselves amongst the Holy Ordos. No one knew how many other heretics were wearing the Inquisitorial Seal. There could possibly even be some that directed the Grey Knights themselves. A Grey Knights Battle-Brother knew that it was their place to leave the thinking to the inquisitors, but how could they trust them if they delved so deeply into the corruption of Chaos?
Sometimes a Battle-Brother questioned if the other half could ever be won. A Grey Knight Chaplain was there to ensure their troubled Battle-Brothers and assuage any doubts, for during their centuries of service they have led Grey Knights through every trial of the mind that Chaos could inflict upon them. The Archenemyʹs atrocities knew no bounds, and only men like them could stop him. In a Battle-Brother's moment of doubt, all they had to do was reflect on the fact that the Emperor continuously sent the Grey Knights to the bloodiest battlefields of the Imperium. This was no mere coincidence. By throwing themselves into those battles and butchering the daemon, they would see the Forces of Chaos broken and fleeing. A Battle-Brother had to take these victories and immerse themselves in them, letting victory blot out everything else. By glorifying in it, all doubt would vanish. The enemy had made a grave mistake in bringing the fight to the them, for the Grey Knights would punish that mistake.
