Basically everything in this thread, but here are the basics:

• Where the Rangar base is.
• An inside "man" in the hospital. (Spoilers, it's Mai.)
• Zeloph is indeed over a hundred years old, and was once called the "Thunderer".
• The scientists tried to harness the power of the gods, nearly killing one in the process, and caused the miasma to leak from the gods' plane of existence into this world.
• The miasma outbreak and the energy crisis one and the same.
• Some Rangar can channel the miasma, like Zeloph. Other members are their sympathizers.
• The Rangar used to be part of the city, but were shunned by many due to the "Carriers" and their abilities.
• Their excursions into the city and hacking incidents were supposed attempts to reach the player characters and tell them what's really going on. Lightning uses the word "supposed" strongly.

Lightning will tell Noel, Steve and Bucky, but only Noel will know where the base is, and Mai's involvement with the Rangar-- the other two will only know that there's someone in the hospital who is a sympathizer, but she's willing to show them where the base is if they ask really nicely, and as long as they don't out its location to the wrong people, or tell others without informing her about it. If you want your character to know what Lightning knows, we can work something out!
