The Comet of Lasair

"Are you sure of this Lasair?" Devon Wyrdsmith asked of the lord arcanum, "I cannot say I know of the consequences, but the risk you'll bear will be significant to say the least." His arcane companion paid the lord relicator no mind; Lasair's thoughts solely focused on the task ahead of him. 
Devon leaned heavily on his relictor staff as Lasair continued to recite the incantation. The staff's collection of trinkets, bones and artefacts began to tremble as if seeking to break free of their holder. A gush of arcane energy poured forth from the chasm as a giant sphere began to rise from the abyss. The air was electric with pulsating magical energies, almost tangible and physical in form.
The lord relictor could sense it like a flood of memories in a torrent of visions; a fragment of Azyr laid hidden in this meteor. Their brother in arms had been dying in this strange quasi-realm, but not to return to Azyr so that they may be born anew. No, they had died a mortal death, having no flash of redemption to usher in their reforging so that they may return to fight on once more. For once nearly immortal beings, the thought of being mortal once more was terrifying, especially as new dangers greeted them with each rising of the day. This fragment of their homeland may be the answer to their despair.
The sphere continued to rise out of the pit, suspended by the tendrils of arcane might from Lasair's lineage. The lord arcanum shook with concentration, his sigmarite mask almost twisting with the immense effort. Surrounding him, the chamber had been decorated with scrolls and sigils of blessings and prayers. Between the two of them, they had spent nearly a full year etching the runes and magic circles onto the walls to make their efforts come to fruition. The ones who had inhabited this place before them revered this meteor, but it is only those wrought by Sigmar's hand who know what power it had hidden within.
The meteor was nearly perfectly spherical, smoothened by it's descent through the heavens and boring into the ground. It radiated a purity that only the Stormcast could appreciate. Even the smell of it was reminiscent of Azyr. As this fragment of their homeland hung in the air, the scrolls begin to flutter and glow as if resonating with its presence. The orb begins to spin, breathing in the arcane powers of the runes and scrolls surrounding it until it is lit aflame in an azure glow.
Lasair breaks the flask containing the spirit of a great Blink Beast. Its soul is quickly absorbed within the meteor, finding new life within this heavenly rock. At the same time, he pushes forth an energy from within himself, forcing it to fuse with the meteor along with the soul of the blink beast. With a final utterance from the lord arcanum and a blessing made by the lord relictor, the meteor blazes upwards with the same force that it came down with, lighting the sky with it's twin tail as it begins to streak across towards the horizon.
Lasair the ever-burning, collapses to the ground, tearing the sigmarite mask from his face to heave gasping breaths. Devon offers a hand to his brethren, pulling him back to his feet. "You've done well Lasair, but our work is not done. The chamber will need preparing for the first souls that are taken back if things go well. It is no Anvil of Apotheosis, but it may save our brothers' souls for the time being." His eyes look upwards to the spiraling staircase that brought them here, but the sputtering coughs of his companion brings his attention back.
"Considering what we've just managed to do mon frère, I zink I have earned a few moments reprieve, non?" Lasair sighs, his weight quite apparent on the lord relictor. Devon looked up at the face of his companion and for the first time could see visible signs of aging, sending an uncomfortable shiver down his spine. He frowns beneath his skull masque, a pang of guilt wounding his pride as he thinks of the ramifications that their task will have upon his ally. 
"Yes, my friend," he answers hoarsely, "a well deserved rest."
