Gauntlets of Ultramar

The Gauntlets of Ultramar are an ancient pair of Power Fists, accompanied by a set of ornate shoulder plates (compatible with both Artificer Power Armour and Terminator Armour) and a set of built-in Bolters. Their true origin is unknown, all that is known is that they were taken back from a fell Champion of Chaos by the Primarch Roboute Guilliman of the Ultramarines. Only the Chapter Master of the Ultramarines, currently Lord Macragge Marneus Calgar, is permitted to wear them into combat. They are stored in the Temple of Hera, the Ultramarines' fortress-monastery on Macragge. They are found in the Temple of Corrections' Shrine of the Great Primarch, where the mortally wounded body of Roboute Guilliman himself is kept in stasis.
