The '''Temple of Correction, ''' is where the [[UltramarineUltramarines]]'s vast northern polar fortress that contains the [[Shrine of Guilliman]], a vaulted sepulchre where the body of [[Primarch]] [[Roboute Guilliman]]'s body resides. Many The Temple of Correction welcomes millions of pilgrims visit every year, as the Shrine of Guilliman is one of the most holy places in the entire [[Imperium]]. The Temple is a miracle of construction and typical of the attention to detail to which the Ultramarines apply themselves. Its proportions defy the human mind by the scope and grandeur of design. The multi-coloured glass dome that forms the roof is the largest of its kind. Even the Techno-magi of the [[Adeptus Mechanicus]] come to marvel at the structure said to have been designed by Roboute Guilliman himself. According to the Ultramarines, there is enough marble within the temple every yearto build a mountain, and sufficient [[adamantium]] and shining [[plasteel]] to construct a sizable warfleet.
