There are now the five nations confederate lords standing with joined hands in a circle. this signifies and provides that should any one of the confederate lords leave the council and this confederacy his crown of deer's horns, the emblem of his lordship title, together with his birthright, shall lodge on the arms of the union lords whose hands are so joined. he forfeits his title and the crown falls from his brow but it shall remain in the confederacy.

in this excerpt, the word “lodge” the readers understand that
a disgraced lord’s crown and birthright will remain a part of the five nations, even if the lord leaves.
a disgraced lord will be stuck in the confederacy and will not be allowed to leave.
a disgraced lord may accidentally leave his crown in the arms of the other lords as he leaves.
a disgraced lord must fight the other lords in order to take his crown and title with him when he leaves.
