Crystal Guardian

The Crystal Guardians were magical constructs spawned by the Shadowjumper to prevent practical progress of the pursuing party of the Hero of Arhok. He left them in the lava caves beneath Fortress Emarard to block access to the displacer leading to Mount Kreth and the Great Clock. 
Each one was tied to an impenetrable mass of crystal that  blocked the path; to clear the jam, its respective Guardian had to be destroyed. The Hero was clued in to their existence by the Goblin merchant Neener, and their destruction was the last recorded quest in the campaign journal.
They resembled oversized Shards, and attacked the same way. There were four of them, in order of weakest to strongest: one purple, one yellow, one orange, and one ruby.
