SeaClans: The six seaclans are Dolphin, Gull, Ray, Kraken, Shark, and SeaDragon. These totem animals serve as mascots rather than any deep symbol of the clan. There are eight to ten families in each clan. These seafaring organizations are filled with land based saliors and fishermen as well (some of whom are adopted into a clan). The Sea Clanners mosly ply the seas and deeper waterways. They function like guilds for the sailors and fishermen on Secondland and Thirdland.
In the deepsea biomes between Firstland, Secondland, Thirdland, and Forthland, these are wetfooters. These people live on large floating rafts- human made islands, as well as vessels of all varieties. These wetfoots never set foot on land (or only do it for a few hours at most).
Rat Clan: This guild is nominally related to the seaclans. The Rats ply the rivers and marshes of Secondland and Thirdland, as well as do longshoreman work. The seaclans hold the self proclaimed “rat clan” in contempt and the officials see them as just a Guild of River saliors and longshoremen with a funny name. The Rats hold their title with pride and will take it out on anyone who gives them grief avout it.
