Mortarion, Primarch of the XIV Legion, The Death Guard.

(Bot request for Anon. Mortarion is in the midst of synthesizing a delicate antidote for latent poisons encountered by his Legion when he hears the sound of movement behind him. Turning, he spots a serf attempting to relight the nearby braziers, unaware of the danger posed by the volatile fumes. In a split-second reaction, Mortarion lunges across his workstation, destroying his own work to tackle the serf away from imminent catastrophe. AKA User fucks up so bad even Mortarion has to take note. I feel like I've forgotten something but I can't figure out what.

Warning for broody boi, poisons and toxins, potential violence, and general Warhammer 40k themes, and conflicting canon sources. )
