In ArcheAge Chronicles, the Throne of Hinnon Dungeon Key is in a “Key Pouch” on top of the Sunken Ruins – the small ruined island in the bay north of Seaglass Beach in Diamond Shores. You get up there with your glider. The key opens the gate to the Throne of Hinnon dungeon to the east, by the Altar of Seals. It is the only dungeon playable in the Steam Next Fest demo (as of October 2026).
Overview: key, quest giver and dungeon
Everything you need is close together in Diamond Shores:
- 1 – Key Pouch: on top of the ruins at the northwestern tip of the Sunken Ruins, reachable with your glider. Show on the world map
- 2 – Throne of Hinnon: the dungeon entrance east of the Altar of Seals. Show on the world map
- Lumina: the young archaeologist at the Guard Campsite who starts the key quest.
- Ironfang Golgius: the boss in the Seaglass Tower after whom the key story continues.
How to get the Dungeon Key
The Key Pouch is not in the water but up on the ruins – at the northwestern tip of the Sunken Ruins, where the long ruined wall juts northwest into the sea from the island. The easiest way there is your glider: fly onto the ruins and land at the northwestern end. The nearest Nui statue stands on the ruined island itself, about 120 meters away.
The pouch holds the Throne of Hinnon Dungeon Key – exactly one, at 100 percent.
The key in the main story
The dungeon is part of the Diamond Shores main story. In story order, three quests lead there:
- A Dark Summoning (quest 10 of 120): in the Seaglass Tower you summon Ironfang Golgius with a binding stone.
- Words of Warning (quest 11): after the fight, the story continues with the key you found.
- The Key to the Forgotten Throne (quest 12): talk to Lumina at the Guard Campsite. The quest requires the Dungeon Key and ends with you opening the gate of the Throne of Hinnon.
If you are missing the key, pick it up at the Key Pouch by the Sunken Ruins. Every story quest with a checkbox is listed in the main story.
Where is the Throne of Hinnon entrance?
The entrance is east of the Altar of Seals in the northeast of Diamond Shores, inland southeast of the bay with the Sunken Ruins. The nearest Nui statue stands at the Altar of Seals (about 150 meters). With the key in your inventory, you open the gate there.
What awaits you in the dungeon
Throne of Hinnon at a glance: for 4 players, enemies at level 30, final boss Helkum, King of Hinnon (level 30) plus one elite enemy (Loyal Hinnon Officer). Clearing it grants 4,000 EXP, 2,000 gold, Ancient Soldier’s Helmet and Ancient Soldier’s Armor. Helkum always drops a Corrupted Heart, plus Faint Armor Tempering Stones (80 percent) or Faint Weapon Tempering Stones (20 percent).
Every enemy, the loot and the location are on the Throne of Hinnon page of our database, and every dungeon of the demo is listed under Bosses & dungeons.
Tip: Two more items lie in the water of the same bay – a Drifted Fishing Rod and the Glider No.7 Wreckage. With your glider and a short swim, you grab all three in one trip.
