Hysionide Crystals

Where these are from, and even the origin of the name remains a mystery. Some believe that they were found by the Knights of the Astral Sea, others that they are a transplant from The City. Wherever they hail from, these strange formations have fascinated adventurers and tourist for years. So what are they? Hysionide Crystals are either sentient or containthe minds of some long forgotten race. However they refuse to help with anything greater than "Where did my sunglasses go", even when it directly threatens them. Some speculate that they are unwilling to interfere out of religious or personal reasons - some variety of "it's your time, not ours", while others think that they are simply bored, and may actually welcome destruction.
