Aquila has a quest to collect a trinket from the Submerged Trench. This guide on Where Is The Submerged Trench In Summer In Mara will tell you where the trench is located as another character, Saimi, also asks you to venture into the great blue to find a submerged necklace.
The quest from Aquila asks you to find a Shipwreck in the Submerged Trench. However, when you first get this quest, it’s very unlikely you have the ability to complete it. You must progress with a different chain first. Continue doing quests in the Koa Quests tree, where you help Saimi to make a map. Once the map is completed, you can begin exploring the areas surrounding Qalis using your boat. It’s at this point you can find the trench and complete both the Koa Quest and Aquila’s Quest.
Where Is The Submerged Trench In Summer In Mara
This is the first quest that requires underwater diving. This particular quest is not the Submerged Trench, this is for the Submerged Necklace for Saimi. Head to Puni Cave and inspect the flag icon. Using the diving goggles, dive down to grab the chests.
After that, you can head South to reach the Submerged Trench. Dive down here and you will find the Shipwreck item you need to complete the quest for Aquila.
