Upon repairing his damaged portal, Trazyn finds an ancient Gloriana class ship in the webway. Devoid of power he enters the tomb ship by force. Green light creeps over power armoured bodies of a legion unknown even to him. Entering the chapel he finds more, chest plates split, leading up to the altar where above it hangs a colossal tapestry woven from precious metals a battle. Ullenor.
The Emperor of Man, Robute, Horus, Jaghatai...and one more.
Walking closer, contemplating how he will save this piece of art if not the entire ship the crop of corpses thicken. The entwined limbs of a nail and tooth fight almost concealing an emblem he does know - the Vulka Fenryka.
He looks at the unknown giant in the picture for a long time and can almost feel him looking back, his eyes shining as bright and keen in the low light as the edge of the power glaive he holds.
Looking back into the dark for millennia. Looking back at his dead sons as his primarch brothers look at their father. Looking back...
Ancient human Kings used to fill their tombs with wonders and riches and lost it all when it was discovered but the clever ones learned a trick. They built two chambers.
He turns on the spot. The giant in the weave is looking right through him. Deactivated stasis caskets, contents of holy weapons taken in desperation, cables dangling like dead sea creatures. All except one. Dark and concealed in shadow, he marches towards it and plunges an open hand into darkness. Metal grasps metal in a resonating confirmation.
The dark clings to the weapon and is wrenched from its grasp, snapping cables like petrified tree roots. Holding it up to watch the edge glint like it's owners he waits, and waits, ready to turn around and...a low bass metallic sound of a distant God's hammer striking an anvil behind him. Striding up to the woven battlescape he can't help but light his path with the enthusiasm of his own eyes. There! A gap. The lock disengaging the final act of an incredible sentinel power cell but not enough to open. Eager to see the secret hidden he touches his metal face to the edge of the adamantine blast door the tapestry concealed and with one optic peers in.
