“Kaer Trolde is the main fortress on the isle of Ard Skellig. For centuries it has been the an Craites’ seat and jarl Crach an Craite’s pride and joy. Partly carved from the solid rock of the isle’s highest mountain, it makes a strong impression on all who behold it. Legend has it it was built by Grymmdjarr Iron Fang, son of Hemdall and Heulyn, founder of Clan an Craite. Grymmdjarr wanted a way to watch over all of Skellige to ensure no harm would come to his brothers, rulers of the other islands. So he wrapped heavy chains around a mountain resting on the sea floor, pulled it to the surface and placed it on the island of Ard Skellig. In seven days he carved out of it an impregnable fortress whose lofty towers afford a view of all the archipelago.”

These nordic, viking like people who live on these islands live off of the ship wrecks that wash up onto there islands shores. The largest island in Skellige is called Ard Skellige, this is the home of Skelliges largest cities and fortresses, Kaer Trolde.
This long lived castle nested in a massive cliff edge has stood as the home for Skellige most fearsome tribe. Other tribes live on the main island but none are as large and dominant as the Kaer Trolde Clan. There king, Bran who led his clan with an iron fist; Passes away as you first land into this town.

Skellige Ilse
The conflicts between tribes have been common over the centuries, however each civilization of people on this island all have the same values. They worship the land, and believe that the gods gift them with plentiful food and hunt. It is because of this that they fight for there honor, and to please the gods that gift them with life.
Your time on Skellige is long, and drawn out, but this is the location for the conclusion of the games story, and is a large place holder for after – game events. Personally, Skellige was my favorite area in the Wither 3, due to its vicious monsters and rugged landscapes.
