The Measure of the Hellknights

[TritonOne]

Does each Hellknight Order have its own The Measure with content unique to that order? Or is the content of The Measure the same and shared amongst the Hellknight Orders? Do the Council of Lictors amend The Measure? Or does each Hellknight Order amend and create its own The Measure? For example, The Measure of the Order of the Rack has a unique set of laws amended by members of the Order of the Rack.
