When it was, there was a White Dwarf article with some background, line-art work, and unit entries for Grey Knights Terminator Squads, and the Grey Knights Terminator Captain. These unit entries were meant for use with that original 1988 army list that was included in the Realms of Chaos: Slaves to Darkness book. Not too much later those Grey Knights Terminators got their own metal models, too (for the Grey Knights in power armour of the Rogue Trader era, you were supposed to use the RTB-01 plastics, and whatever other lead Marine models were available, just like any other Chapter). Several of the various Inquisitor and the Daemonhunter Inquisitor models hailed from the Rogue Trader era, as well.
