Second aspect of the endings is about the game world. Geralt has great influence on it. There are four options related to rulers of various lands: Nilfgaard, Northern Realms and Skellige Islands. The last option shows the fate of Geralt after the story ends.
Northern Realms -Reason of State quest.
Three endings are available, depending on who should become the ruler:
- Radovid - For the current king to remain the ruler you must ignore the quest
- Dijkstra - Sigimus can become the ruler. Sigismund. For that to happen, complete the quest and after killing the king remain neutral (let Dijkstra kill Roche);
- Nilfgaard's rule - in this option Nilfgaard must win the war. To make that happen, after killing the king, ally yourself with Vernon Roche against Dijkstra.
Nilfgaard - Emperor Emhyr fate
Two options are available, both linked to the previous ending. Whether Emhyr survives depends on who will win the war. If Nilfgaard, then Emhyr survives, otherwise Radovid or Dijkstra will rule.
Skellige Islands - quest (King's Gambit)
Skellige Islands up to now remained neutral side of the war conflict. You can change it or leave that state, depending on decisions made in the quest.
- Cerys side - Skellige Islands remain neutral
- Hjalmar side - islands join forces against Nilfgaard
- Bran side (ignoring the quest) - rules on Skellige changes and civil war starts.
The last ending is related to affairs in the game, more specific to affairs with Triss and Yennefer. Depending on which one of the sorceress you have chosen, Geralt's hsitory will change. Both options give a positive ending. Of course you can try to have them both... but it's an option that ends with negative ending and the hero remains alone.
