Beneath the surface of Kyndera lies the Undercroft—a vast, hidden world carved into ancient stone and illuminated by slow-pulsing veins of green light.

These glowing veins run deep through the rock, carrying a quiet energy that gives life to the creatures who dwell here. The Undercroft is dark, but never empty—its silence is filled with subtle movement, soft echoes, and the faint shimmer of bioluminescence.

This is where the CryptKyn reside. Often misunderstood, they are not creatures of fear, but of balance—guardians of what lies beneath. Formed from bone, shadow, and mineral, they move slowly and deliberately, perfectly adapted to their hidden world.
