Once you have **The Forge Unknown Key**, you’re one step closer to getting the Arcane Pickaxe! There are two contenders for the best pickaxe in [The Forge](https://www.roblox.com/games/76558904092080/The-Forge) – see which one we recommend in our [The Forge Arcane Versus Demonic Pickaxe](https://www.gamezebo.com/walkthroughs/the-forge-arcane-versus-demonic/) guide.

## The Forge Unknown Key

For a key that’s supposed to be unknown, we sure do know a lot about it.

### How to Get the Unknown Key

To obtain the Unknown Key, you first need to complete a **side quest** from the **Bard NPC** in **Stonewake’s Cross**. This quest is ‘*The Lost Guitar*‘, and it requires you to find the Bard’s missing guitar. Luckily, while it’s hidden, it’s pretty easy to find once you know where to go.

1. Speak to the **Bard** sitting by the **campfire** in **Stonewake’s Cross** to start the quest
2. Next, head into the **caves** of Stonewake’s Cross and **turn left** as soon as you reach the two NPCs
3. Look to the **left** to see **moss** on the floor with **leaves**
4. Head over to it and walk on top of it to **fall through** into a **secret location**
5. There is a **skeleton** in this cave, and the **lost guitar** is to the **right** of it
6. Interact with the guitar to pick it up and climb up the ladder to get back to the main cave
7. Follow the pathway out of the cave and walk over to the Bard NPC
8. Speak with him to hand over his lost guitar to complete the quest
9. The Bard gives you the **Unknown Key** as a reward

### What is the Unknown Key?

The Unknown Key is a usable item when unlocking the gate to the **Fallen Angel’s Cave**. What’s the importance of this secret location, you ask? Well, this is where you can purchase the **Arcane Pickaxe**.

This gate cannot otherwise be opened without the Unknown Key. Even if you don’t want the Arcane Pickaxe, which I do recommend getting, it’s still a good side quest to complete! You never know, the Fallen Angel’s Cave might have more importance in future updates.
