You enter the shielded chamber deep inside your flagship (or command fortress) through quadruple-secured security doors. The room is utterly silent, causing every step and every breath to be clearly audible. There are several rows of high-quality hololithic projectors arranged along the ceiling and walls of the small, highly shielded room. They are inert - until all four security doors have locked and the internal scans are complete. Then they awake to a mechanical life, projecting the hololithic images of persons into the rooms. The image is of an unheard of quality. Not even a single flicker, no annoying delay between visual and auditorial transmission. Were it not for the faint smell of blessed machine oil and ionised air, you fall to the illusion that your conversation partners are at your side in person.
The technological wonder is all the greater for the latest status report of various ongoing campaigns arrived just prior to this regular meeting of the highest Commanders of the local Imperial forces. Status reports that traveled through several astropathic relay stations until they are reduced to night incomprehensible word-garbage. And it took them days if not weeks to arrive on your desks, rendering them even less useful.
Compared to this long range communication - which is the Imperial standard, rather than a simple case of bad luck - the communication method provided by the Archmagos feels near miraculous. Instantaneous communication with all connected parties heedless of the distance with full visual and auditory of all communication partners - truly a technological wonder blessed by the Emperor.
Ripping your gaze and thoughts away from the technological wonder, you focus on the present Commanders...
As the miliseconds clicked over onto meeting time Archmagos Archimandrites Primus Dominus Inveniet Fulcrum appears in the room. He retains much of his human form at first glance. While many Magos turn into nearly insectile beings with segmented bodies and fervent additions to their aumentation, Archmagos Fulcrum has chosen to eshew much of that route. This is not to say he isn't heavily augmented. In fact, only his brain is still organic, and even that is supported by an array of internal cogitators and processors. On his back, sprouting like a spider, are all kinds of mechadendrites and servo-amrs equipped with tools for any job. His face is relatively featureless, consisting of a flat, metal mask with glowing "eye" receptors protecting a staggering array of other sensors. He still walks on two feet, but those have been upgraded to handle forces that would crumple a standard human. His arms now operate on levels that would make an astartes jealous and his core houses a powerful plasma generator that powers his tactical form when in use.
He waits for the other commanders who are inevitably several miliseconds to several whole seconds late. He forgives them as he loads up the reports he needs to share. Not everyone was as blessed my the Omnissaiah as he.
