I've never thought you can get Trio of 9999 earlier than Calm Lands.
Seems, High-Summoner-Lady-Chloe is still far from Calm Lands, I put this in spoiler tag.
(SPOILER)When I first reached Calm Lands, I rent a chocobo to get to Remiem Temple. There, I race for Cloudy Mirror and 30 Wings to Discovery. Mix 2 of WTD, and you'll get Trio of 9999.
