A Sith burial shroud was a fabric covering used to dress Sith mummified remains for the funeral rite.
Frequently, Sith shrouds were adorned with spells and inscriptions rendered in Sith hieroglyphic writing. Garments referred to as "Wraps of Frost" functioned as these shrouds, soaking up the deceased's malevolent energy and accumulating power from it across vast stretches of time.
In the year 24 ABY, Luke Skywalker discovered a fragment of a Sith shroud alongside the Book of Sith, which had belonged to Emperor Palpatine.
