Glory Holes Of Oblivion is a mod for Elder Scrolls IV: Oblivion that allows shooting arrows and casting spells through holes in gates, letting enemies do the same.
NexusMods classifies Glory Holes Of Oblivion as containing 'adult content,' possibly due to a lack of understanding of glassblowing terminology.
The term 'glory hole' originally referred to a place where things are heaped disorderly. The term likely originates from the Scottish word 'glaur,' meaning 'to make muddy or dirty.'
The term 'glory hole' also has historical references to glassmaking, such as reheating large objects and creating a circle of light. The term's modern usage dates back to a 1707 court case.
