Spoilers: Game hunt and the Shadow King jacket. The novel's vengeance is not given an ending here.

Nagarythe on the hunt
Alith Anar is High Elf Free-LC. The February 2023 FAQ prints him on the Warhammer II row and again beside Alarielle on The Queen and the Crone. Nagarythe marks enemy characters for rewards, prefers ambush, and moves by the Shadow Realm. He shoots. Mislead leaves a decoy. Shadow Walkers are his skirmishers.
Spearmen and Lothern Sea Guard are the line those skirmishers need when the enemy arrives. A marked lord on the far side of a hostile border is still a campaign risk. The reward is not a reason to take every fight.
Prince of the Nagarythe
Shadow King is Gav Thorpe's Time of Legends novel, the second book collected in The Sundering. The English ebook says his family is betrayed and slain, and that Alith Anar, prince of the Nagarythe, walks a dark path while Ulthuan is in civil war with the druchii. He becomes the Shadow King and hunts from the dark on a vengeance that will not end.
The PDF states the same jacket and names Gav Thorpe. The omnibus calls him the wrathful avenger whose spirit will haunt the druchii, and it sets him between Malekith the usurper and Caledor the reluctant Phoenix King. Caledor in that trilogy is not Imrik. The English jacket stays with the betrayed prince and the hunt.
Two hunts
Marked for Death in Immortal Empires picks targets on the campaign map and pays for them. The novel's hunt is the civil war that split the elves, told from Nagarythe after a betrayed house. One does not complete the other.
Malekith's own novel is the start of that split. Shadow King is the avenger's book. A Nagarythe campaign that confederates Ulthuan is a sandbox result.
