It took me over a month being pretty much solo except some of my clan members collecting castaways with me, defending the island, or claiming islands to help collect cash for it.It has a central island with a castle, farm, arena, bar, and docking area.It is heavily defended with a ring of walls with towers on the natural spires and cannons on it, it has towers on the entrance too.There is a little secret area in each of the main sections of the base.(ran into the decoration limit making the castle btw)

Initial Plan
The plans were made about a month or two before the empires update, some things were changed such as the double docks.
Farm
the farm grows a thorn flower, 2 saint lilies, and 2 golden apples along with wheat and sugarcane. It has the home to the farms that work here, and has a small area to relax and cook
Bar/Tavern
this is the bar, it is where the clan goes to have a good time, it has a ladder to some storage, and a food store NPC.
Arena
this is the arena, people can host friendly 1v1s and fight here, it also has a small spectating area.
Docks
the dock has the barracks(tier 4 because if not it’ll get annihilated), shops(auctioneer,blacksmith, armorer, and enchanter,fishmonger,builder,and shipwright) with a good amount of detail(shipwright,fishmonger, and builder have backboards to look like shopkeeper huts and less like stands).
Merchant Camp
Tailor & Dyer, for cosmetic customization, and it is kinda based off the Samarian merchant caravan
Castle
The castle has a decently detailed path up to it, it has a dining room and meeting room.
Secrets
since you made it this far, here are the secrets
Credits and other things
Credits to my clan for gathering galleons and some castaways for me, as well as helping defend it during the building process(wall complex was upgraded at the end of the initial building phase), few months after i started revamping the main island cuz it was lacking an farm for reagents, and it looked awful.
