Required quests
Main dialogue
I don't think I can totally trust you... but maybe that's the reason why I can let you work on this. I want you to see 2111002 in a 3rd person's point of view, unaffiliated with the past of Zenumist and Alcadno, what he wanted, and make a decision on whether it was the right thing to do.
Accept
Apparently, just before he went missing, 2111002 had been in close contact with a suspicious character. Have you heard of 2111007? ...he's a man with a very questionable reputation. Regardless, I also hear that he is very trustworthy in business deals, so I think he'll be good. You may get some information on 2111002 through him...
Oh, and... know this one thing. 2111007 loves money. He doesn't even speak to people that don't have a substantial amount of mesos with them, so I highly advise you to prepare some before the meeting.
Decline
Are you too afraid to encounter the truth? If so, then there's nothing I can do... maybe it's a wise thing not to pursue matters on 2111002 any further.
Main dialogue
...Just tell me what you want, and I'll get it for you. An item? Information? Dirt on someone? Just tell me anything, and I'll get it for you. What? A missing alchemist? You mean, 2111002... ? Hmm... yes. He frequently visited yours truly just before his disappearance. Anyway, what about it? What? You want some information on 2111002?
Accept
Tsk tsk... This is definitely an unexpected source of income. This is good! Now, as promised, I'll give you the information on 2111002, as long as you're ready to pay me. Come see me when you're ready.
