Sanctuary of Ice: The Greater Alps, the source book dedicated to The Greater Alps Tribunal is a Fourth Edition work, so at least some adjusment is necessary. Also, unfortunately, little history is presented for the two domnus magni, though present day situations and recent history is provided. The House Jerbiton section of Houses of Hermes: Societates provides some Fifth Edition information about Valnastium, just as Sanctuary of Ice contained some information about House Jerbiton. The House Criamon section of Houses of Hermes: Mystery Cults has less information about its Domnus Magna.
