A number of these Space Marine Legions for 40k have these pages. It's a split. Warhammer 40000 has the largest main page, largest character page and even the individual marine chapters manage long pages.
On top of that, Warhammer 40000 is more than just one work. Each faction can be the focus of their own army book as well as Black Library novels. These novels will then have their own recurring tropes due to the nature of the focus faction.
