Thank you for not adding anything intelligent, Rikku.
On another note, this is a question that could clear up future questions, can you get the Caladbolg on the first visit to the Calm Lands, or do you need the airship?
From what I know, Nirvana can be obtained on the first visit (win Cloudy Mirror, backtrack just a little to Macalania and make it Celestial, and then go back to Calm Lands), and since Nirvana is in the Calm Lands, I hope the same applies for Caladbolg.
