Crystal Cave is the fifth level of Sonic and the Black Knight for the Nintendo Wii. Eroded from the grassy rocks of Titanic Plain by underground rivers, Crystal Cave is a labyrinth of voluminous cavern systems. Giant, spiral stalactites jab down from the rocky ceiling, while on the cave floor giant blue crystals and bioluminescent mushrooms grow within the subterranean detritus.

StoryEdit

Although he should be making haste to complete Nimue's quests in order to free the kingdom from King Arthur's tyranny, Sonic is instead determined to answer a child's plea by preventing a crowd of villagers from becoming dragon food. After racing across Titanic Plain, the hedgehog arrives at Crystal Cave, where the beast has for now simply imprisoned the Arthurian folk.

Dashing through the caves and through hordes of Arthur's troops, Sonic sets the villagers free, and everyone escapes before the dragon returns to feed. Strangely enough, the felled beast is not justly slain until Sonic (or the other Knights) slays it before they reach the barrier stone.

Returning back from The Highlands with Nimue's deadline long past, Sonic finds the distraught child to tell her that her family is free, only for it to be revealed that said child is Nimue in magical disguise. The Lady of the Lake tells Sonic that by helping the "child", Sonic has fulfilled her last quest: offer compassion to those in need. Returning to her home in Deep Woods, Nimue agrees to at last tell Sonic how to defeat King Arthur.
