Warrior's Hill

Warrior's Hill (オハ丘のネオス, Oha Hill's Neos) is a dungeon featured in Golden Sun: Dark Dawn. Located on Harun Island, it is composed of three watchtowers, which are full of mechanisms and Zol blocks. After reactivating the third and final watchtower, its treasure can be obtained using the Watchtower Key, a gift from Ikan. Warrior's Hill is connected to Harun Channel via an underground cavern.

Story
Warrior's Hill was apparently created in ancient times by the Jenei, ancestors of the Adepts, as part of a response to a potential Grave Eclipse. Within Warrior's Hill, the Jenei hid an Artifact known as the Third Eye, a treasure meant to help guide warriors stop the Grave Eclipse. The room containing the Third Eye was locked, and the towers buried beneath the ground by an unknown mechanism. In the passing years, a prophecy would be handed down regarding a future Grave Eclipse. The prophecy not only foretold the Grave Eclipse, but also told of those destined to stop it: "Warriors who wield weapons that are not weapons", i.e. Adepts.

After fleeing Belinsk, Matthew's party arrives at Harun Village. After saving the son and grandson of the local storyteller, Ikan, Ikan tells the group of the prophecy surrounding Warrior's Hill. He reveals that one of the towers spontaneously emerged following the start of the Grave Eclipse. After providing the Adepts with all the knowledge of the tower he knows, Ikan gives the Adepts the Watchtower Key needed to access the tower's treasure, and sends the Adepts to Warrior's Hill.

Matthew's party travels through Warrior's Hill, eventually causing the two other towers to rise from the ground. Upon reaching the final chamber, they are puzzled to see the treasure is an apparently ordinary rock. Though puzzled by the rock, the group decides to take it anyway, knowing that the Jenei would not have hidden it without a purpose. After leaving Warrior's Hill, the group leaves Harun Island in search of more answers.

Warrior's Hill: Initial Visit
Go into the only building here and down the stairs. Here enter the left door and go down the ladder, jumping on the platform to descend. Make sure to jump off to the left for the Cookie in the chest. Continue down the device and move all the way to the left (past the door). This will take you back to the canal.

Harun Channel
In here keep going left for quite a few screens. You'll get to the dead end from earlier, so get down into the dry area and push the block into place, then freeze the two puddles. Now you can go back up and use the ice pillars to get near the boulder and crush it. This will clear the way for the sea to fill up the channel and start another set of gears. Go back to Warrior's Hill now.

Return to Warrior's Hill
Now you can ride this close set of gears. Go through the door here and up the stairs and jump on the ledge. Now ride it around once so that you start descending. You'll see why in a second as a chest comes into view. Jump over to it to grab the Dragon Mail. Now ride it up all the way and jump off to the left. Get to the right hand side (you can walk on the gears here) and go up the ladder into the nest room.

In here, go through the left door and use "Move" to push the gear down. You're going to want to backtrack as well to get down there so you can push the gear into the nearby gap. This will start up the other side of gears and make a new building open up. Go up these new stairs and climb the tree to the left. You can now reach the Venus Djinn up here, so after a short fight welcome the Venus Djinn Chain to the team.

Go back down and take the door in the center circle. Move the gear down and into the obvious recess in the floor, then launch yourself up there with the see-saw. Use the gears and go down a floor, where you can get an Aegis Shield from the chest. Go back up using the door.

Now use the see-saw to continue (ignore the second one). Move around and find another gear to move into place, which will raise the last building. Go back to the hub and use the stairs to go up. Up here, enter the door with the watchtower key and view the scene. Hmm, quite the rock. Well, despite not knowing what it does for us, grab the Third Eye and depart.
