A mysterious affliction contracted by long-term marrow handlers, causing patches of living tissue to gradually harden into fossil-like bone.
Prolonged exposure to raw titan marrow triggers the Calcification Sickness, which slowly transforms flesh into calcified material. Early symptoms include joint stiffness and chalky skin patches; late stages can immobilize victims as entire limbs ossify. The Order of the White Candle maintains hospitals for afflicted miners, but no cure exists. Some cultists view the sickness as a blessing — a sign of the titan-gods claiming their faithful.
