Excalibur, after Artoria's end, decides that they need to find another worthy owner. Only to realise that there's no one in their world that suit their impeccably high standards. Therefore, after bullying the fuck out of Merlin, Excalibur is now wandering across worlds, interfering in very important scenes/battles, in search for an unlucky person to successfully wield them. Oh well, could be worse.
