"It is during our darkest moments that we must focus to see the light." Only a few were given the privilege to focus on it. And even less beings achieved the ability to emit the light. However, the way to revelation is a lonely one. Many fail to survive the first stage of infestation. They either go crazy and take their own life driven by fear and exasperation, or they reveal themselves before stage two starts, and they turn into laboratory rats. There isn't much choice in the end. Only the ones with strong wills can bear the pain. Unfortunately, as we know, the human being is a rather weak lifeform, and it's nature urge it to fight against foreign organisms, such as the incubus.
Therefore, the human is a bad host in their eyes. They'd surely select a superior being if there was one, rather than using the 'least evil'. It's our gift for humanity. Eternal life. Increased body regeneration. Telepathy. Those are gifts, given by gods. They rule Sirius. Of course they try to keep humanity in their believe, and manipulate them, so that they'll never ally oneself against us. We keep them weak and ignorant, being a minimal threat to us. Once the time has come, they will return, and repeat history. The Suncrusher will be ready. And so will we.
But first, the requirements for the return have to be performed. Everyone plays a role in this plan. Mine was to infiltrate, manipulate and infest the target. Now the observation has started. There's not much we can do for him now. I gave him the light, but he has to follow it by himself. I've sent out guards, which will secure his survival without letting him know. The third eye will watch his steps. And soon, he, Louis, will be rewarded. An 'angel's kiss' knows no return. It is final. The progress can't be stopped. They'll be pleased.
