Not much has been written about the Legio Custodes in recent times.
I guess it would be a boring read to write about soldiers guarding the Emperors throne room.
What I am interested in knowing is What is the name of current Master of the Legio (M41/42)? Traditionally the head of the Legio is also one of the High Lords of Terra so there has to exist a record of who it is somewhere in all the books, e-books, short stories, White Dwarf, pc games, etc. that seem to be coming out of Games Workshop at an alarmingly fast-paced intervals.
