[WH40K] What Space Marine Chapters do not follow the 1000 member rule?
gpt
The Black Templar are famous for not following the Codex Astarte.

When the High Marshal (sort of like a Chapter Master) is asked about his 'chapter' size, he simply replied "Not enough."

There is about 5.000 - 6.000 Black Templar divided by several crusades. This is probably the reason they are allowed this, they are basically never a united fighting force (as that was the reason of the Codex Astarte 1.000 Astarte rule).
