1. Nature and Geography of the Realm
A Crystalline Environment: The Crystal Dimension is a parallel plane where massive, jagged crystals sprout from the ground in place of traditional trees and plants, creating vibrant, glittering landscapes, crystal corridors, and cavernous structures.
The Crystal People: The dimension is inhabited by native, sentient crystalline beings and guardians that protect the realm's powerful artifacts.
Methods of Access: The dimension is normally sealed off from the physical world, but it can be breached through specific mystical tethers—most notably via the consumption of rare items like the Crystal Gem Apple, which instantly teleports individuals into the plane and binds them to the realm's crystal energy. Specialized crystal-shards and artifacts can also tear open stable dimensional portals between Ooo and the crystal realm.
2. The Rainicorn-Dog Wars
Territorial Conflict: Long before modern eras, the Crystal Dimension and its surrounding borders served as the primary battleground for a bitter, prolonged territorial conflict known as the Rainicorn-Dog Wars, fought between native canine populations and migrating or rival factions.
Post-War Shifting Society: Though the ultimate victor of the ancient war is ambiguous, the aftermath left the dimension heavily stratified. In the post-war generations, mainstream societal structures and institutional power within the dimension largely fell under the control of the dog population, setting the stage for deep cultural friction.
3. Counterculture and the Anti-Establishment Era
Youth Rebellion: In later decades, the Crystal Dimension experienced a socio-political counterculture movement. Disaffected youth populations—predominantly young rainicorns—formed underground anti-establishment circles, staging protests, pranking canine authorities, and running beatnik cafes.
The Radical Factions: While many participants treated the rebellion as a passing phase of youth, radical fringe figures within the movement harbored intense, extremist hatred toward the dog population. This radicalism culminated in attempts to unearth and weaponize dangerous military contraband—such as the Crystal Mergence of Destruction—to permanently alter the balance of power in the dimension before loyalist intervention successfully secured and removed the catastrophic weapon.
