Throne of Hinnon

Key, then altar

Whisper of the House describes the key route. The key sits on an upper platform in the Sunken Ruins. The route the guide describes starts northeast of the Watchtower of Hope and uses a glide onto a side platform among the pillars. The key is uncommon, weighs 0.1, and cannot be sold or destroyed. The entrance is the Altar of Seals, not the platform where you picked the key up. Glide height changes the exact landing, so “the pillar side” is the stable part and the jump itself is not a single pixel.

Inside, the guide describes four sigils and one lever before Helkum. I am not redrawing their screenshots. If a sigil does not light, the usual report is a missed earlier sigil, not a second key.

Helkum and the reward row

RaidDex’s reward line is 9,000 experience, 2,000 gold, and two items. That is a database row for the Early Access version at level 30. The demo version was a different difficulty, and a guide that says “go at level 8 or 9” is talking about the demo, not this row. I will not merge those levels.

Keys are not shared across a party. Each person needs their own. The multiplayer page explains the same rule for other key items. If you wipe, the official note on instance progress says a disconnect keeps progress; it does not say the key is refunded.
