Crystal Peak contains extensive tunnels throughout the mountain which were used to mine its crystals. The crystals are present across the entire area, with some tunnels having crystals lining the top and bottom of the cavern. Conveyor belts can be found in many rooms which transport the crystal shards.
In the centre of Crystal Peak is a Bench with the boss Crystal Guardian. Its second form, Enraged Guardian, is located above this room, although the Monarch Wings are required to access it. A Mask Shard can be found after this boss fight.
A lift to the northwest of Crystal Peak connects the area to Dirtmouth. On the summit of the mountain stands a statue of the Radiance which holds a Pale Ore. In the east part of the area are tunnels filled with old mining golems, one of which contains the ability Crystal Heart.
In Hallownest's prime, Crystal Peak's mines supplied the kingdom's cities with a constant supply of crystals. The crystal ore contains energy, not as powerful as Soul but less lethal. Besides regular bug miners who mined the crystals with their claw-picks, creatures such as the Shardmites and Glimbacks were used to carry around carts and machines.
The crystals themselves have a strange power hidden within them. They glow in the darkness, and there is a bright point of searing heat inside each of them. The crystals can refract light and also emit a very soft singing sound.
How to access
Crystal Peak can be accessed from two rooms in the very east of the Forgotten Crossroads. One room has a toll gate leading to Crystal Peak which can be opened for 50, but it requires the Lumafly Lantern to be able to interact with it. The other access point to Crystal Peak contains a breakable floor which can be destroyed with Desolate Dive.
Sub-area: Hallownest's Crown
A statue of the Radiance stands at the precipice, looming over the town of Dirtmouth. It contains a rare Pale Ore.
Hallownest's Crown is accessible by either using Monarch Wings or bouncing off enemy projectiles.
Sub-area: Crystallised Mound
Crystallised Mound is an ancient abandoned temple found deep within Crystal Peak which is older than the mines surrounding it. It was home of the Snail Shaman's fourth aunt who became encased in crystal after meditating too long within. Breaking the crystal she is trapped in grants the Descending Dark Spell.
Entering this area requires Desolate Dive to break the floor. The Lumafly Lantern is recommended for the dark area right before the Mound. Crystal Heart or the Monarch Wings is also required to cross the chasm leading to it.
