Glass Witch Kieln, a glass maker and sculptor

Her entire body is made of glass and bundle of glass fibers woven with her hex

Those enchanted glass fibers won't ever naturally fall out or crumble so you don't have to worry about inhaling glass particles or how fragile her body would be. Instead you better watch out to not touch her without some proper protection since those sharp fibers will definitely shred or punch holes in your meager flesh

Other than that she's a pretty chill and amiable character to get along
