Dream Crystals

Dream Crystals are small crystals that lovers exchange so they might dream of each other. They appear in Ultima VII Part Two.

Description
Rabindrinath once collected many of these to make a single large Dream Crystal, which caused the rift in Gorlab Swamp, that trapped the souls of all the inhabitants of Gorlab inside the Dream Realm. This was ultimately destroyed by Siranush and dream crystals ceased to exist on present day Serpent Isle.

Trivia

 * Edrin wears a Dream Crystal.
 * A larger, immovable dream crystal shape can be found inside the game. This suggests that maybe the player was initially intended to break it.
