I've known for a while Nordok never died. The Imperium couldn't function without him. Everyone's out for themselves; without him to keep them in check, without the threat of destruction from something greater over their heads, they'd all tear each other apart in no time trying to take control for themselves. Since I learned to harness the cosmos, I could...feel...something. Familiar. Distant, but close, like invisible eyes just over my shoulder. I can mask my presence so he can't sense me psionically, but I wouldn't be surprised if he had other ways. Technopathy. Possession of nearby bodies. Snitches. Whatever.
Just as I know he lives, I am sure he knows I've defected. Unlike the others I can't live in the palm of another and content myself with the thought that "at least I'm alive." Soon enough, they'll get their chance. I am the greatest of all. I am a force of nature. Beyond Ancients and Goddesses. How they react to a greater force looming overhead...
She approached in the most direct way possible. Flew herself across the cosmos alone on her own power to meet her maker. Visually minuscule, she nevertheless doubted she would not be located and recognized by at least one means of detection. She was counting on it. To ensure that Nordok himself would be aware of her arrival, she opened her mind to the telepathic detection for which he'd been well-known as she descended upon the desolate world.
Pausing in atmosphere, she waited to be acknowledged in some way. To be met with a hostile or non-violent welcome. Either or, it didn't make much of a difference to her. Not like barely feigned diplomacy and threats behind a totally transparent veil would make much of a difference from an open attack to break through. A few minutes of her time, maybe.
