This letter does look like it contains something worthwhile since it is written in codes. This looks quite complicated, but I am confident that this will be a piece of cake for Lilin. Please hand this over to her.

So you're saying that a member of the Black Wings was already reading this letter? Then we have to assume that the Black Wings know the contents of the letter as well. It may be written in code, but I'm sure they have someone that can decipherit.

Eh? This is quite urgent. What's going on? Are you planning on hanging out tonight with Athena Pierce? She's busy, too, and I am not sure if she can afford to set aside some time to hang out with you.

Tru told me you even ventured to the past for some valuable information. Have you come back, Aran?
1) (You explain the events that took place.)

I see. So this letter contains more information on the Seal Stone? Can you please show me?

Wow…this one contains a complex set of passwords. This will take some time for me to decipher, but once I get that taken care of, I'll let Tru know. In the meantime, please keep training!

You still haven't gone to [map 140000000]? If you want to get there before the Black Wings, you'll need to hand the letter to Lilin immediately!

Aran? Tru told me you ventured into the past for some valuable knowledge. Have you come back? Tru told me I won't be disappointed this time around…

Ahhh, Aran, why did you drop something so valuable like this? You know very well how important this letter is! Good thing I got it back. Otherwise, what would have happened? Here, hold onto it tightly and head over to [map 140000000].
