Crusader (Stanton II) is a low-mass gas giant in the Stanton system, United Empire of Earth (UEE). Rare among gas giants, Crusader's upper atmosphere is breathable by Humans and supports an active indigenous biosphere.

The world was purchased by Crusader Industries from the UEE in SEY 2865 and is now the company's headquarters. It was settled via a complex network of floating platforms that had been constructed by the UEE Navy in 2855 as repair drydocks for its capital ships.
