You are indeed mistaken.  The 1RR agreement timed out a long time ago and only concerned Oathkeeper.
Westeros.org is not an unfit source.  Its use in these GA-rated articles has gone without comment for years and it's practically textbook expert under WP:SPS.  If you don't like it, take your concerns to the discussion on talk:Oathkeeper and the RSN noticeboard.
Stop trying to bias the RSN discussion by deleting precedent.  You're already up for this on AN/I.  At least wait to see what the admins have to say about your edits.  I am not the only one reverting you.
