The White Sentinels is a Loyalist Space Marine Chapter of unknown Founding and origin. It is known for its affinity for dangerous close assaults.

During the Era Indomitus it was reinforced with Primaris Space Marines by the Torchbearers' Task Force White Sentinels commanded by Admiral al Pre'golsa.

Al Pre'golsa inflicted such stinging defeats upon all he came across that his fleet's name came to be feared by pirates across the Karenna Sub-sector.

When the admiral finally encountered the doggedly surviving White Sentinels, al Pre'golsa had inadvertently secured a deadly new reputation for his fleet as expert naval tacticians to be avoided in void combat at all costs.
