Ok so here is the first mission after you join when you are just Mud.
Your mission is to prove that you can be a useful and loyal member. Each member has had to do this exact quest. The quest is to go to a specific dungeon and reach the end, but you will not be given the location you will have to find it using help from citizens and possibly other members if they choose to help. You end up learning that it is a famous dungeon when speaking to the citizens of the city since none of the members would talk about it. So you go to the dungeon and fight your way through a variety of enemies, the final one being a swarm of cliffracers. Once you defeat the cliffracers you reach the final room. There you find an elderly mudcrab with a long beard, a cane, and a large book. He is one of the first mudcrabs in the guild. He then speaks to you the history of the guild and the greatness of mudcrabs. Then afterwards you receive an even greater appreciation for mudcrabs because of what you just went through. You go back to the guild headquarters with a token given to you from the mudcrab as proof, a coin with a picture of a mudcrab engraved on it. The symbol of the group. You speak with the quest giver to end the quest.
