So to set the stage, I present The Scar Crusade, which is based on a small crusade (seven figures) accompanying a Mechanicus Explorator fleet, as depicted in the McNeill "Lords or Mars" trilogy.
Two of the figures I did not model as one Kul Gilad, Reclusiarch is in Terminator armor and the other Auiden is an Apothecary.
The five models I started out with represent the crusade after a specific point in the story line.
Given that it would be a small number of figures, I also decided to true scale them using the Doghouse technique of adapting Cataphractii terminators and converting them to Mk. III armor equivalents. I am a big fan of the Mk. III set of armor.
The Scar Crusade
Brother Sergeant Tanna - He is described as having a beard and a widow's peak, which I thought interesting enough to model. He is the only member without a helmet on.
Yael - Described as the newest member of the crusade, recently promoted to initiate, favored by the Marshal, seems to desire to prove his worth to his more experienced brethren. So I tried to give him a slightly different pose, be it impractical or not, as a way to convey his individuality and style. Also, when he sparred with Magos Dahan, he fought with his chainsword and a combat knife.
Issur - If I am remembering him correctly, is a recognized bladesman, but did not receive the Emperor's vision and therefore did not get to become the Crusade's champion. There is a certain level of resentment in him about that. I opted to give him a fairly standard pose to represent his "I don't like what happened, but I am still a Templar" attitude.
Bracha - I made Bracha the comms guy because I was running out of names and slots for story/game roles.
Zion - Not in the story, it seems from battle reports I've seen, this additional firepower would be helpful.
Aetius - Another non-story character added to potentially provide tactical options to the team. Besides, it's hard to burn witches if you don't have a lighter.
Atticus Varda (Emperor's Champion) - Oddly, he is not the best bladesman in the crusade, Issur is. Yet he received the vision. He is described as wearing more ornate armor than his brethren and a laurel on his helm made out of ivory.
He is the only member of the team without battle damage.
It was observed by Tanna after a big fight, that although he was in the thick of huge battle they were leaving, he did not have a mark on him. I thought that comment interesting enough to want to model it.
