Hello

I have a few questions about guilds:

1. Can anyone tell me all the organisation types?
2. Do anyone have a suggestion to a good object for a guild? Not like just being rich or something, but some more, related to the story or something.
3. And what can I do to make a cool event? Any suggestions?
4. Is there usually any guild fights? How do they work? And where?

That was my questions, thx for answering!
