Firstly, If you dont know how to make a guild im sure you dont need to make your guild at this moment.
Really.
If you cant even find out how you make one it will be just waste of your time, money and efforts. Just join one that already exist but i don't really see you playing this game if you cant find out simple thing like this.

Secondly, wrong forum, New Recruits, a place where you ask questions.

And last but not least, Spiral Knights wikipedia is your friend.
