Crystals are valuable artifacts found in the tunnels of Stormhold. Although prisoners are supposed to give all crystals to the overseers, many keep some for themselves and they are often used as a form of currency. The Warden overlooks these indiscretions as long as the prisoners do not become greedy. He is only interested in the Storm Crystal, which he believes can contain all the evil of the Empire.
There are two types of lesser crystals to be found:
- Filled Crystals - Enchanted with useful effects. Can be traded.
- Hollow Crystals - Used to remove corruption.
