Night Lords/Heartwarming


 * At the end of Throne of Lies the Night Lords find what they were looking for, An army of supersoldier Grimdark Batman-on-crack actually weep.
 * In Soul Hunter the human navigator Octavia is being tortured by a bunch of prisoners liberated by the Black Legion. All the prisoners hear is a heavy footfall, nothing faster then a sedate walking pace. Octavia smiles and says "he's coming for me". Talos is calmly walking down the hall massacring anyone who is stupid enough to get in his way. Why? Because she's his slave and he always protects his slaves. It's heartwarming in context.
 * In Blood Reaver, when Octavia is in Septimus' room, she finds a number of pictures Septimus had drawn of her.
 * In Blood Reaver Talos needs to, and calls upon Cyrion, Mercutian at first, and then, after a moment of thought, summons Xarl, realising he actually trusts him. Considering they are all heretic astartes and of the Night Lords, this is a huge deal.
