From the Scriptorum, Entry 01: Hand of Fellner

An intelligence briefing on the feudal world of Margard and its most steadfast enforcer.

The world of Margard hangs like an emerald jewel veiled in perpetual mist at the very edge of the Koronus Expanse... Millennia ago... a fateful warp jump... would forever alter their destiny.

• SUBJECT: Calix von Fellner, the "Hand of Fellner." Scion of a noble house marked by a unique heritage.

• WORLD OF ORIGIN: Margard. A feudal death world of perpetual mist and geothermal activity, whose human population was subtly reshaped by a warp-meld with Terran hounds during its founding.

• RULING DOCTRINE: Dominus-Law. A feudal system mirroring the strict hierarchy of a wolf pack, where status is maintained through constant displays of physical, psychological, or strategic dominance.

• CULTURAL KEYSTONE: The Ghoulfang. The planet's apex mammalian predator, a monstrously mutated descendant of the original colony hounds. From these beasts are harvested Grave-Pelts—macabre mantles of hide and bone worn as the ultimate symbol of status and power.

“The mist coiled thick and silent around the battlements of Grymmwatch Keep... Calix von Fellner paused his step to take note, the jagged, tar-pitch spines of his Grave-Pelt stark against the gloom. He scanned the shifting veil below, mismatched eyes narrowed, the unnatural white streak of the Fellner Moon starkest of all... Vigilance was second nature here; weakness, a simple invitation."

But what happens when this world of rigid, primal law is confronted by the labyrinthine politics of the wider Imperium? What becomes of a man like Calix when he is claimed as an asset by powers whose games are played across the stars?
