Black Moon Merchant Guild

Black Moon Merchant Guild
The Black Moon Guild, apparently this guild has stood the test of time far longer than one might think its root stretching back all the way throughout The Final Empire . Oftentimes the branches of the guild are not plainly in sight, most of the time located in the Eye of the Storm a big underground network present in lots of major cities.
But on the surface many other merchant guilds are just extensions of the Black Moon Guild, and operate in line with the conglomerate.
The guild however is a bit eccentric, despite its size not everyone is granted entry, only those with sufficient skill in a certain area of expertise is one granted entry. often the guild also Judges the potential of certain individuals. Furthermore there are now class restrictions one could be the most powerful King yet still be denied entry if the guild judges you to be insufficient.
The major branches are divided into 7 layers, and most people have only ever been allowed entry into the first 2 - 4 levels everything above is mostly shrouded in mystery and most think its just a sham.
