Ah.  I wasn't entirely sure on what to answer.  Now that you made it more clear, I'll be happy to answer them better.

1) Standard indistinguishable-from-magic devices include advanced holograms, augmented reality, and complex genetic modification.  Dolorrites use shard weapons (coilgun type weapons that fire toxic shards) and hard-light weapons (anti-armor, imagine laser and plasma combined).  The Emergence Entity alliance of aliens use weaponry based on or similar to dark matter.  The Dolorrites are considered the bleeding-edge as they rival or exceed the Emergence Entity in technology.  Dolorragh use teleportation, warp drives, powerful robotics, and even synthetic life forms.  So despite the fact that their anti-personnel weapons are designed to kill in the most painful ways, they have better vehicles, logistics, and espionage.  IE: Dolorragh outguns and outmaneuvers the EE.  The only advantage the Emergence Entity has would be numbers.

2) Playable species are humans and Dolorrites only for now.  Though if you don't mind being at risk of gruesome torture, feel free to play as a different species.

Though if you want to make your own alien, do let me know.

3) Griffin is the ragtag human resistance that I mentioned.  Ragtag bunch of misfits those people.  Dolorragh is the city-state of the Dolorrites.  The Emergence Entity is the alien collective.  All three of them play significant roles.  Also, what the EE has as their ultimate goal is to enslave humanity, collect the Earth's resources, and solidify their power among other sapient species.  Griffin wants to liberate Earth from the clutches of the Emergence Entity.  Depending if your character is a human that lives in the city OR a Dolorrite raider, there would be different degrees of influence.

The difficulty of the RP will depend on what species you choose.  Dolorrites are the Easy mode.  Other non-humans are medium difficulty.  Humans are the hard mode, unless they play it smart.  I'll also PM you more info as needed.  I'm on the Discord too.
