Oh you made it here. Let's cut to the chase. There's a Mount that's different from all other Monster Mounts available only to the Cygnus Knights. Unlike the regular Monster Mounts, this Mount uses Mimi.

Go to the Hatchery that follows Training Forest 3, and you'll find Kiridu the Mount Trainer raising the Mimis for Mounts. Go up to him and learn the intricacies of Mounts for Knights. Of course, this is for the glory of the Empress.

I have just written you a letter of introduction. Show him the letter, and Kiridu will teach you about Mounting. Hopefully the next time I see you, you'll be riding one of those.

Hmm... do you honestly wish to keep moving from place to place with just your legs?

Hmm? You must be a newly-minted Knight here. Are you here to learn how to Mount?

Psssh, Neinheart. She doesn't need to write this letter, since it's obvious whoever's coming to me is probably from [map 130000000] anyway.

Have you yet to go on to Kiridu yet? Then let's pick up the pace now. It's not like [map 130000000] is a huge island that is a tough to navigate. Don't tell me you can't find the Mimi Hatchery. Really?

Hmmm..., I do know that you're a Cygnus Knight, but... without ... I can't do it for you. We need to keep a standard of formality in here, and I can't process this until you bring me the letter again.
