Taking the Ossuary moon of Vittoru- Grimm omens campaign

Ossuary moon of Vittoru- Grimm and his flottilla approached the warp wracked world of Vittoru.  The planet a former shrine world now engulfed in the great rift was awash in warp energy uninhabitable and hostile to all life.  Grimm made for the planets moon which had been converted into a collosal Ossuary for the hallowed dead and pilgrims of Vittoru.  Here was where Socratus was holed up.  The Ossuary moon would be a perfect base of operations for Grimm and his warband.  The vox came to life and Grimm listened as Socratus contacted him.

     "Massive warpstorm on the surface, deposited daemon army.  Managed to ward this cathedral.  Wards are holding but we are under siege.  Again requesting assistance.  By the eight.... they have..."

The vox cut out replaced by the daemon princes growling voice.

     "Grimm we meet again.  You cost me dear and the time has come for a reckoning.  I had to make a new pact with a new master.  Your fall shall Herald my rise.  He will witness it and our compact will be complete and the power your soul shall grant will see me drown the stars in blood.  I am waiting for b you Grimm!" The daemon prince roared.

    Grimm ordered his forces to the surface.  He would complete his task for Abaddon and link up with Socratus and vanquish this princevof the warp once more.

Grimm advanced his force amid the warp storm.  Each strike of lightning deposited more and more daemons.  The cruel laughter of the daemon prince echoed in the air.  A lance of warp lightning hammered the moon before grave Tithe Colossus leaving a skittering horde of bloodletters.  The daemon engine opened up engulfing them in fire from its furious guns.

Daemon cavalry thundered around one side of the warded cathedral while more daemons closed in.  The daemon prince flew into Grimm and his chosen hacking apart two of the chosen in his frenzied fury.  The chosen struck back with accursed blades that bounced off the skin of the daemon prince who laughed.  Grimm prepared a blast of warp energy that dissolved as he watched a clutch of horrors arrive and he saw what stirred behind them.  There striding up the street was Vashtor his eyes upon Grimm and the daemon prince a mocking smile upon his face.  Grimm felt the cold terror of realization hit him.  Vashtor was the daemon prince's new patron.  He was outmatched.

    Grave Tithe Colossus targeted Vashtor but as it fired Vashtor raised his hammer pointing it at the Defiler.   The daemon engine's guns suddenly erupted in flames as shells exploded in their breaches.  The explosions rocked the daemon engine back wounded by the sudden malfunctions.  Harkon moved then leading his squad within the warded ruins to join Socratus and his followers.  Grave Tithe Colossus settled back on it's legs and sensing Grimm in danger dartedvto the side.  It slammed into the daemon prince bearing him into the dirt ash and bone dust.  The daemon prince howled in surprise and fury for a single heartbeat before Grave Tithe Colossus snapped it's claw around the fiends neck.  As the daemon prince was decapitated it's essence boiled back into the warp.

The daemon cavalry swung around behind Grimm and his force and charged the venomcrawler.  Beneath a avalanche of daemon hooves and blades the smaller daemon engine exploded.  Vashtor stalked towards grave Tithe Colossus radiating dark majesty.  With a few swings of his hammer the Defiler fell before the greater daemon a burning wreck.

     "Grimm quick into the cathedral!" Harkon screamed over the vox.

     "NO" Grimm roared.  Rage coursed through him. Rage over Grave Tithe Colossus and at Harkon for his presumption.  He would not fail.  He would vent his terrible wrath upon these foes.

     "You can not win this by force of arms!" Harkon screamed.  " This requires warp craft, your warp craft!" 

     "Go Grimm he is right.  I will buy you the time to win this for us!" Brutus the helbrute board as he raced forwards guns blazing as the helbrute slammed into Vashtor.  Grimm burst in the warded ground and began to draw deep upon the warp.  A beastmen shaken joinedvhim adding his strength to Grimm.  A heartbeat later Grimm felt Socratus add his power.  It was more raw warp power than Grimm had ever wielded before.  He saw Vashtor smash Brutus into the ash and bonedust set to deliver the final blow.  Vashtor suddenly looked at Grimm sensing the vast amount of warp power Grimm had tapped b into.  Vashtor lashed out with his claw lightning fast.  The claw lifted the helbrute up on his feet.  With a twitch of his claws the Helbrute would be gone forever.  It was a stand off.  Then a vox distorted rumble emerged from Vashtor.
