Forum:SH:Source request (Droids, Technology and the Force)

In his endnotes for Droids, Technology and the Force: A Clash of Phenomena, Abel G. Peña mentions that in Section 1 of the article there is a reference to the Force-sensitive river stones from Qui-Gon Jinn's home planet introduced in Jedi Apprentice: The Hidden Past. Could someone with an access to the article post the relevant passage here, since I have no way of getting my hands on it myself? Thanks! Tinwe (comlink) 09:12, December 11, 2011 (UTC)
