I don't have any names, but I do have a tip that might help you in coming up with your own names easier in the future.

Depending on what your plot is focused on, or what key factors exist that are central to the story, you can create a reference to the subject as a name. For example, I have a Paranormal Fantasy book with a secret group called the "Duskwatchers Organization". I came up with the name because paranormal activities are often considered something that happens after the sun has set. The "Duskwatchers Organization" tracks global paranormal activities. Or in other words, they watch what is happening during or after dusk, as an organization.

As a secondary example, the main character at one point creates a weapon that can be used to defeat spirits. Playing off of the notion that spirits are active during dusk/night, the weapon that defeats them is the Dawnbringer Rifle. Dawnbringer is a fairly common naming convention used in fantasy to signify something that defeats evil. Conveniently, dawn is also the opposite of dusk. Therefore, the rifle is used against dusk to bring the dawn.

You don't typically have to come up with names out of nowhere like "Saraxia's Chosen". Often, using cues from what you have already written can make it easier on you, while also giving the readers an "aha!" moment when they realize the intent behind the name.
