I’m one of Arthur/Morgana’s ride or die stans. They are the most epic pairing (romantic or platonic) in Arthurian mythology. The Merlin writers have done a great job of making Merthur veeeeeeeeery close but Armor owns me because I loved them first and love them best.
But… slash O.o Granted, my OTP in the legend is ‘ArMor’ but in the Merlin series… it’s ‘Merthur’. It cannot be different...
