Spoilers: Game prison and the 2020 pack. No Age of Sigmar.

Yvresse, the cage, and Athel Tamarha
Eltharion requires The Warden and the Paunch. In Immortal Empires he leads Yvresse. The Warden's Cage can take an enemy lord or hero beaten while the effect is on them. Prisoners go to Athel Tamarha for interrogation and other decisions. Building that place strengthens Yvresse's defences, its mists, and the Mistwalker troops.
He fights, casts High magic, and can ride the griffon Stormwing. Spearmen screen. Lothern Sea Guard cover an approach. A flying mount is a target for missiles and for troops that are good against large creatures. The capture still starts with a fight he can reach.
The warden and the paunch
Warhammer Community's 1 February 2023 archive piece remembers the fourth-edition starter. Grom led goblin spearmen against the High Elves. Opposite him was Eltharion the Grim on a gryphon. Grom's side of that scene is a chariot pulled by three wolves, with the standard bearer Niblet.
The 7 May 2020 FAQ puts the same pair into Eye of the Vortex and Mortal Empires, not into the Vortex race, and calls them eternal nemeses. Eltharion leads Yvresse. Grom leads the Broken Axe. Release is 21 May 2020. In Immortal Empires the purchase is still that lord pack. A player's victory over the Broken Axe is not the starter set and not the FAQ's collision.
Other High Elf lords around the warden
Alarielle's Avelorn is another defence of Ulthuan, built on the Everqueen rather than a prison. Imrik's Knights of Caledor hunt dragons. Aislinn's November 2025 note includes Eltharion among the six lords who can receive dedicated conquests from the Sea Patrol.
Aislinn's list is a Sea Patrol gift. It does not move Yvresse. Grom's lore page carries the starter and the FAQ from his side of the same pack. A prisoner in Athel Tamarha is this campaign's catch.
