Just my thoughts.

I've been on sites where groups function in a pretty similar way. You have a leader, some sort of chain of command, and a limited amount of members. The site I'm thinking about is actually the ADBZ site I used to rp on. Some inspiration could be taken from such systems. I feel like this could work really well for Althanas. So basically do it like this: Leader/Chain of Command, then X amount of loyal members. I am okay with limiting the number of people who can join a PG. I'm fine by that. What I'm suggesting to is make a regular chain of command type of idea. That ways, if whatever PG system is currently in works comes into fruition, then you can have it function in some similar way to that.

I'm pretty flexible about the chain of command idea. I think that it could work like this as well: one leader, and one or two chain of command people to follow the leader sort of deal. There's a lot of potential here for that. A guild structure should be flexible but definitely have a sort of theme they are built around. Themes/goals/etc. I'll chime in as I come up with more ideas, but hopefully my suggestions are useful to you guys!
