Main dialogue
You're here. I'm sure 1101002 told you the gist of things, so I should forgo the details and... but you look like you need the details again. Sigh. As you are well aware, Ereve is an island protected by Shinsoo. No evil presence may enter the island, and even if it were successfully here, they'd be immediately detected and removed from the premise.
The problem is, we were unable to find him this time. It's simple, really. The thief was actually 9001009. 9001009 1104001, an important member of the Black Wings. We were unable to spot him because of his ability to transform himself to another being.
The treasure is an important item that shall NEVER end up at the hands of the Black Mage. 9001009 has yet to escape Ereve, so join the search effort. 4032179 will be needed to conduct the search, so go visit 1101002 first.
Now, I want you to defeat 9001009 and bring back the treasure.I, as well as other Knights, will also be searching.
Accept
9001009 is most likely disguised as one of the Knights. The appearances may change, but the inner self won't, so I suggest you keep talking to various Knights until you hear something that doesn't sound like it would come from a Knight. If you do, you can consider that individual 9001009 and attack immediately.
