Forum:Questions for Borderlands fanfiction... eilyahjenee

So I'm writing a fanfiction that takes place 200 years after the first Borderlands. It'll be about an OC Vault Hunter, and she's going to be a Siren. At the beginning, she's traveling alone, but she meets someone to travel with. These are all the problems I'm having right now:

Those are my main problems right now, I may ask more later. ;D
 * On the Sirens page on this wiki, it says all the Sirens have a unique ability, but I'd like for my OC to have Phasewalk. I want to stick as close to the canon as I can, so one of the first things I need is a new "phase____" ability. I've thought about Phasewarp, which would be damn close to Phasewalking, just quicker,but I'd like some other ideas as well.
 * Also, I need ideas for new creatures. Names for em would be nice too. I have a snake based animal, that had two mouths,one on top of the other, but I can't think of a name. I'd like it to start with an "L" though...
 * And, I'm wondering if the Destroyer, or something else, should be there in the Vault. I'm thinking no on the Destroyer, because, well, it's dead. But should there be another creature there?
 * Should I make different designs for the Bandits, or essentially leave them the same? (If you're wondering why I'm talking about "designs" a lot, it's because I draw the characters/creatures/etc. and I'll put them on DeviantART so if people want to see how the character/creature/etc. looks, they can go there)
 * I've also been tossing around ideas of how much influence Atlas still has on Pandora. I'm thinking either the same amount, it's diminishing (as in they're pulling out or being pushed out by another company), or it's another company entirely. I'm leaning towards it's diminishing because it's being pushed out, but I like to hear others opinions to.
 * This is a HUGE problem I've been having. Apparently, the rotation of Pandora is over 90 hours long. Apparently, Pandora gets all of it's daylight from light reflected off it's moon. APPARENTLY, it takes many Earth years for it to revolve around it's sun. Here's my dilemma... If it only gets light from it's moon, that means that the side of the planet we are speaking of never faces the sun... right? Now, for that to happen, the speed it revolves around the sun HAS to take the same amount of time for it to rotate entirely. If you still don't get what I mean, think about our moon. We ONLY ever see the one side of the moon, because it ROTATES once fully at the same rate that it takes it to REVOLVE fully around Earth. Soooo.... which should I go with? Should they have ninety hours days (45 hrs of light, 45 of darkness), getting it's light from the sun, or should I pretend it revolves around it's sun every 90 hours as well, and have it gets it's light from the moon?

Then when I start putting the story up, I'll add a link to it so EVERYONE can see what they've helped me with. XD (Oh, and as many creature ideas as possible would be GREAT!)
