Furibundus

“A lamp of fervour shines upon the white gate
Not held by the greatest saint to mark the way
But hung alone to banish enfolding shadows
That beset the Emperor’s true servant upon the fated path”
–Translated from the prophetic verses of Abenicus
The light of Furibundus marks the far side of the Great
Warp Storms and the beginning of the Koronus Expanse. It is a huge and primal stellar mass, far
brighter and more energetic than any star should be. Its fires
rage so fiercely that the cataclysmic energies unleashed within
cause vast bulges of burning plasma to distend Furibundus’s
form, writhing as though immense beasts fight within. The
outer envelope constantly tears and ripples, throwing off huge
flaming masses into the near voids. Furibundus is surrounded
by shells of remnant gas expanding outward, each a remnant
of the star’s outermost layers.
The Imperial presence around Furibundus clusters in
two locations: the stonework void-settlement of Footfall,
and the Adeptus Mechanicus temple of Altar-Templum-Calixis-Ext-17. Footfall’s ornate, tethered structures orbit at a sufficient distance from the star to be safe from the lethal
ribbons of solar plasma, and for void-ships to operate with
little impediment. Further inwards, close to the primal roar of
Furibundus, there is a planet set in a frantic orbit and blasted
to molten rock over and again by its proximity to the bloated
star. The only way it can be seen is by the shadow it casts
on the movement of plasma-ribbons. This is Altar-Templum-Calixis-Ext-17, and it is here that the Mechanicus hide a
heavily shielded fortress-temple, within which Tech-Priests
study the secrets of this furious star.
