I've been working on modeling and level design, now that I see the light at the end of the tunnel for that stuff, I've created something that I now just want to basically turn into a guild.

It doesn't have to be a guild per se, but what are some of the steps I'd need to take, just in general terms,

also, can someone explain to me what factions are and how I would use them? Any advice, tips, or whatever would be turtles. thansk!

Firstly learn the distinction between a faction, and a guild. A faction in the CK is basically just a way for you to group NPCs together in order for them to share behaviours, dialogue, radiant story quests, etc etc. So the Bears in Skyrim are in a faction, not a guild

Now you create a Guild by putting people into the same faction. And if you want a hierarchy, that's where faction ranks come in. Pick how many ranks you want (my guild has about 8) and give them each a name. As far as I know though, that name is purely for a CK viewer and means nothing in-game; it's the faction rank number that's important. When you've got the basic framework of your faction set up, then you can start creating NPCs and putting them into the faction (factions tab in Actor window) and setting their rank accordingly.

Next comes quests. You set up which "rank" or NPC can give various quests, set up dialogue to be specific to your faction and/or the ranks in your faction.

After that, you've basically got your Guild Just need to add the cosmetics of it for the player to experience.
