Dragonshards

What the party knows

Fork described these strange crystals as one thing above all else;  valuable.  He explained that they can be processed and used as material components of spells, among other things he wasn't terribly familiar with.
They have identified and collected two types of Dragonshards so far;  Eberron and Siberys.  
Tilly discovered the Eberron Dragonshard beneath a tree in the jungle; a small egg shaped stone whose interior was lined with small pink crystals.
Tilly and Fork both acquired Siberys Dragonshards where the Jungles of Xen'Drik met the desert;  large, golden crystals lodged in the sand.
