[Magatia's Secret] Who is De Lang?

It's a medicine I have had since the day I first opened up my eyes. I had no idea what this was for, so I was going to throw it away, but... for some reason, I had a feeling I should not just discard it like that. I had a hunch that this is an important item, for some reason. Maybe this is for Keeny.

It may indeed be for Keeny, so can I take a look at it first?

Sure! If it's for Keeny, then it's a definite yes. I have the medicine with me right now, would you like to take it?

Then take this and go see Maed of Alcadno Society to have it checked out for the list of components in this. He will definitely know whether the medicine is good for Keeny or not. I am not sure if it really is for Keeny or not, but... if it does help her regain health, then I will be elated.

Are you busy with something? It might be a medicine for Keeny, so please go have it checked out soon.

Good seeing you. Did you go see Humanoid A? Did he have the medicine for Keeny by chance? ...This is the medicine that he has kept since the beginning? Please hand it to me.

You lost the medicine that I gave you before. Thankfully, a friend of mine found it, and returned it to me. No one may know what this medicine is for, but it might be an important one, so please handle it with care as you give it to Magatia.

Have you not gone to see Humanoid A yet? Maybe he might have the medicine for Keeny...

Is Maed not there yet? There's no one in Magatia who is as knowledgeable on medicine as him.
