Ash (VatMas49)
Ash is a vat-grown clone, birthed from one of the tanks aboard the Angyr Angst. The name 'Ash' is a short form of VatMas49, which is his designated number. Kruger spliced his genes. Kruger grew him in a tank. Kruger birthed him Kruger taught him everything he knows. As a result he's more than a little colored by Kruger's view of life - and very loyal to his master.
Ash is tall, slender and hairless, with 'sculpted good looks' (his face is completely symmetric) and a big-time user of antibacterial gel (leaving his skin with a slightly oily sheen). He wears the traditional greenish robes of Kruger's staff, unless his tasks requires him to wear some form of protective gear (or disguise - probably required in his new role as infiltrator).
He has a full cybernetic upgrade package; worthy of a full member of the Adeptus Mechanicus. Additional implants include 2 Mechadendrites (one has a plasma torch, the other a multi-tool), a MIU and a built-in vox caster. He's rarely seen without at least some toolsets, auspexes and sacred dataslates. If combat comes calling he can wield a range of melee weapons; he's no slouch, but he's not Astartes either. Ranged combat is done by a powerful, yet compact las-carabine. He has a suit of light carapace armour somewhere in his quarters; the same type used by naval armsmen acros the galaxy.
Philosophically he's influenced by Uriel (as are all of the crew of the Angyr - Kruger included): There is so much wrong in the galaxy that it has to burn, all of it, so that something new and pure can rie from the ashes. "It is the 2nd or 3rd Terraforming that yields the strongest harvest," is one of his sayings.
In terms of tech-use and techno-lore his good points include: Librarium searches, machine spirit tweaks (including security bypasses), and remote control (he's quite the expert at directing servitors and drones). He's also quite skilled with bio-systems; you cannot be one of Kruger's children and not know these things!
His only weak spots are personal combat; he's got little training and no special combat augmentation. He is also not good at miniaturization; or perhaps he does not really see the need for it. What gear Ash makes or uses is usually rough, plain, clean and utilitarian - nothing overly fancy or ornamented, nothing to detract form the item's true purpose.
If he must contribute in battle he does so best when remotely directing servitors and drones. One of his most prized tech-artefacts is a painstakingly restored Imperium scout drone: A combat-programmed servitor brain housed inside a flying armoured shell. It packs a bolter and a plasma pistol-equivalent weapon (powerful, but short-ranged). It is also quite stealthy and has a good auspex array (so it's good for scouting).
