Description
The Sea Lord Aislinn DLC pack introduces the High Elf naval tactician Aislinn as a playable Legendary Lord for Immortal Empires and Custom Battles. Commander of the Sea Patrol, Aislinn is Ulthuan’s spearhead against Dark Elves, Norscans, and all who threaten the Asur.
Though many nobles find his ruthless methods distasteful, none deny his unmatched naval expertise. His mastery of the legendary Dragonships and the forces they command is Ulthuan’s best hope of survival.
Unique mechanic: Dragonship Fleets
The Sea Patrol does not develop settlements traditionally. Instead, they command Dragonships—vast, self-sufficient vessels with infrastructure, economy, and military buildings. They support nearby friendly fleets and launch major assaults. Aislinn begins with one Dragonship but can add more as his campaign expands.
Unique mechanic: Asur Occupation
Aislinn transfers most conquered settlements to other High Elf factions but retains limited building rights. He can develop Sea Patrol Outposts to strengthen naval forces, or establish Elven Colonies at key locations, both generating resources.
Unique mechanic: Asur Domination
Outposts grant knowledge that fuels upgrades for Outposts, Colonies, and Dragonships. Dedicating Outposts to major Elven factions unlocks aid from their leaders, including elite units and buffs.
New units
Aislinn’s roster emphasizes coastal strikes, alongside the standard High Elf lineup:
- Legendary Lord: Sea Lord Aislinn
