Chapter 3: Olderion: Luka’s Rescue, Lake Dorr & Water Shrine

How do you reach Luka?

Use Cave of Waters’ glowing controls and boats. These alter the local water level and connect boarding points; walking back and forth along the same dry ledge does not bring the missing boat route into position. Nichol joins during this investigation. Follow the cave’s connected passages to the rescue objective and Wave Lopros.

The rescue encounter is weak to Ice. Clear the prey it calls before it consumes them, then return damage to the boss. Its target rules differ from the Water Dragon encountered later in Old Town, so use the two-rescue comparison before changing areas.

Finish all three purification points

Return with Luka and interact at each marked waterway. Completing one site repeatedly does not advance the other two. After the attempts fail to clear the underlying contamination, follow the new objective into Old Town.

Lasswell and Nichol stay behind during part of the rescue. Reassign Lightning and recovery to the characters you can actually field. Head north through the monster groups, speak at the wounded-soldier objective and continue east toward Elle and Arsha. Defeat the Water Dragon, then regroup before the Lake Dorr investigation.

Lake Dorr is a story fight, not Esper recruitment

Destroy the Orbs of Light when they appear, use the resulting opening against Leviathan and clear the orbs again if they return. A single opening does not permanently end that mechanic. The Lake Dorr guide covers this version; obtaining Leviathan as an Esper belongs to Nichol’s later personal quest.

Return to Olderion and stay at the inn after the lake events. The next progression condition is the First Water Maiden’s power in Waterfall Way, not an arbitrary key bought in town.

Reveal and clear Water Shrine

Continue through Amore to Warden’s Cape. Let Nichol and Elle reveal the route, then allow the Warden’s entrance scene to remove the barrier. Inside, distinguish local basin controls from large platform mechanisms. The crate-crossing guide shows when to lower, align and raise the water.

Prepare Lightning for Alluvion and clear Prism Cores before absorption. After winning, return to the Aquapolis, follow the final city scenes and use the southern port objective for Zoldaad Empire Territory. Check the Nichol dialogue comparison separately from the required departure.
