What the Unknown Key Does

The Unknown Key is a special quest item obtained after completing the Bard NPC Quest, where you retrieve the Bard’s missing guitar. Once you hand the guitar back to the Bard, he rewards you with the Unknown Key.

This key serves a very specific purpose: it unlocks access to the Fallen Angel’s Cave, a secret area that contains valuable resources and rare items, including the Arcane Pickaxe.

How to Use the Unknown Key

1. Locate the Fallen Angel’s Cave Entrance – After completing the Bard quest, head to the main cave area where the Fallen Angel’s Cave is located.
2. Follow the Path – Move past the two Quest NPCs, then take a right turn toward the zombies.
3. Unlock the Gate – When you reach the gate blocking the entrance to the cave, use the Unknown Key to open it.

Once the gate is unlocked, you can enter the Fallen Angel’s Cave, which also unlocks an achievement. Inside, you’ll be able to purchase the powerful Arcane Pickaxe, essential for mining rare ores and enhancing your gameplay progression.

The Unknown Key is more than just a key—it’s your ticket to one of the game’s most important hidden areas. Make sure to complete the Bard quest as soon as possible so you can start accessing high-tier items and gearing up for the challenges ahead in The Forge.
