Description
The Orb of Primal Stone is a fortuitous find, but Acadia and Tae'shara have conflicting hypotheses regarding the barrier.
I have my own hypothesis. Perhaps with more elemental orbs an answer will become clear.
One of the explorers saw an oversized water elemental in a nearby cave. Defeat the elemental, and perhaps you will find another orb.
