Horns disease

The horns disease is a non-contagious illness that causes the afflicted's bones to grow horn-like protrusions randomly. The disease seems to be painless but can still be a burden for obvious reasons. The only known person with it is Subni.

The condition is named after The Horns, a city built into large and tall horn-like mountains. While it is said that the disease originates from there, it is unknown if it actually relates to it at all.
