the place Jelle will be staying will stay secret.

  I will give you one thing: it will be a location with a lot of minerals.

  I need help with thinking up different minerals like helium or mithril.

  The genuine version of this novel can be found on another site. Support the author by reading it there.

  so if you guys can help me think up some of them with a little bit of details it would be much appreciated.
