Atramentar

Pretty nifty custom model of an Atramentar. They may not be as fast as their other brethren, but you will still be shitting bricks.

The Atramentars were the elite of the Night Lords Space Marine Legion who were equipped with Cataphractii Pattern Terminator Armour and formed the First Company under First Captain Jago Sevatarion. They were for all intents and purposes, served the same role as an Honour Guard for daddy Konrad Curze, although in reality, Curze wasn't interested in having bodyguards, especially slow-asses like them who could not keep up. So they were regulated as frontline wall-breakers.

Now, I know what you are all thinking. "Slow-ass bulky-as-fuck Terminators in a legion of hit-and-run specialists? How does it work?" Well, this can be best explained that anything that causes terror would suit the Night Lords' MO, and Terminators are fucking terrifying, so they still tick the boxes.

Historical Stuff

During the Thramas Crusade the Night Lords' Batman Daddy Konrad Curze teleported across to the Dark Angels flagship Invincible Reason to exact revenge on the Dark Angels Primarch Lion El'Jonson and ordered Sevatar to take the Atramentar and join him. Sevatar complied and 100 of the Atramentar attacked the Invincible Reason, initially making strong progress until the Dark Angels fought back. Eventually, Curze had his fill in inter-galactic trolling and retreated, but by that time the Atramentar had suffered heavy losses. Not like Curze cared about it or anything.

Following his death of Sevatar, the Atramentar largely dissolved rather than follow Zso Sahaal, who succeeded Sevatar as the First Captain. Some, like Apothecary Talos Valcoran, put this down to Sahaal not being a Nostraman, but according to the Atramentar asked by Mercutian, a member of First Claw, 10th Company, it was mostly because the Atramentar felt no one could live up to Sevatar's reputation and he had formed the Atramentar into the brotherhood they were.

Atramentars are usually equipped with Lightning Claws, but they can carry other power weapons or close-combat weapons such as Chainglaives, Powerfists, Chainfists, Power Swords or Thunder Hammers. Their only sort of ranged weapon seem to be Combi-Bolters based on the crunch, so yeah. They are definitely more on the melee side of things.

Crunch

On the Horus Heresy tabletop, whilst they don't have an official model yet. They do have rules. For an additional 70(!) points over normal Tartaros terminators, these guys are pretty fucking expensive, but you are getting Fear, Deep Strike and Cloaked in Murder. The lattermost rule gives them +1 to charge a unit that's already in combat as well as a +1 to hit if the charge is successful. They come stock with Power weapons and can exchange them for Chainglaives (free), Fist/Claw (5 points) and Chainfist/Thunder Hammers(10pts), while they have the same ranged options as Legion Terminators. If Sevatar is in the army they may be selected as non-Compulsory Troops choices and count as Legion Terminator Squads for the purposes of his Warlord Trait. Ironically, they also have applications in lists without Sevatar, as they can Deep Strike even without him.
