Whispers from the dark
When the Triumvirate first arrived and started to plumb the depths of the Tomb World, they awoke more than just the security protocols of the Necrons. A long forgotten C’tan shard, hidden within the depths of the world, was roused from its millennia-long stupor. When it awoke, it realized that the insignificant specks upon its prison could be used to its purpose. It realized that while it could not fully escape, it could reach out and touch the minds of the mayflies. And through sheer luck, it realized it could take the guise of the very thing they were seeking.
Without the Triumvirate’s knowing, the dragon (for that was the form it decided to take) threw the reawakening sequences of the Necrons into disarray. It also sidled into the triumvirate’s minds, persuading them to take more and more radical steps in order to break through the Necron defences. The melding of Necron technology might have made the Mechanicus physically stronger, but it also made them easier for the Dragon to understand, and to bend to its will.
Soon, the Necron tomb world lay quiet. The Triumvirate had conquered. But in doing so, they unleashed something far… far more dangerous.
For too long have I let the maggots burrow within my world…
For too long have I allowed the scions of Mars to unearth my hidden secrets…
For they have unravelled my prison, and I am now…
