[@Nerevarine]Looks great, albeit this being a fanfic force of sorts, you'll have to write a more through profile on them later. Albeit your intro did a decent job at that and your faction basically seems to be Gulf War era with no exotic techs, fantasy elements or whatever else.
So what do you need to write down?

First, your leader. Your intro said that a group of Immortals were lost and I doubt the Grandmaster was aboard on that ship. You may mention Dariush Kurd in parenthesis as technicall the leaer of the Immortals but your true leader would be whoever the highest ranking memeber in the party of Immortals sent to Worluk.

Second, your military. Normally you may have to talk about your society and the number of civilians, too. But you took care of that by various means. You have to describe your military a bit, though. What kind of military equipment you have? How many soldiers and number of vehicles? Also on a related note keep in mind that as a purely military unit who got lost in Worluk your equipment, ammo and related materials are limited stock you can't really replenish until you can establish contact with your home universe again.

Third, draw a point or a tiny circle on the map where your faction would be. Alternatively if you trust me just describe on which continent you are and from which sea/ocean? Say, you are at the shores of Gerondar from the Middle Seas.
