The shaft, long as Seren was tall, was not wood.  Polished, mottled amber and brown, it looked almost … scaled.  The broad head was of one piece, blade and stem, ground jade, milky smooth and leaf-shaped.  No obvious glue or binding held the socket onto the shaft.

She pulled the weapon loose.  The scaled texture, she saw, was created by successive, intricate layering of horn, which explained the mottled appearance.  Again, she could discern no indication of how the layers were fixed.  The spear was surprisingly heavy, as if the shaft had mineralized. (RG)
