Hülle Granz Cathedral (グリーマ・レーヴ大聖堂, Gurīma Rēvu Dai Seidō, Old Norse for "The Cathedral Which Hides Heaven", German for "Shell Gloss Cathedral", Japanese for "Grima Raef Cathedral") is a field located at Δ Hidden Forbidden Holy Ground. It is one of the Lost Grounds, and may have functioned as a Root Town and a minor event location in Fragment, the beta version of The World. Hulle Granz is a unique field, in that it consists only of a small island with a large cathedral in the center located in a lake of mist. The area's Fragment keyword was "Navel of Lake", and it is said to be an important place from the Epitaph of Twilight. Hulle Granz is the site of many important events in both Project .hack and .hack Conglomerate. Its name means "That Which Hides Heaven."
