After returning the Mint to Poper, everyone is cured of the plague. But I'm told that if I don't stop the source of it, everyone will just get sick again. Makes sense actually. With the Star Staff & Duma's Key in tow, I now confront the boss of Siegfried Castle, Duma (if the key's name wasn't an indicator of that).
From there, I exit out to the Gnome Tree, were I find the town of Litaly, Here I learn about the Ice Cave nearby and how I need the help of Nymphs to reach Lagoon Castle, but lo' and behold, Demons are trapping them inside. But of course I knew that already.
