The Xylan, six-limbed humanoids native to the nearest stable reality, speak of Xenolithe as the "Echo of Infinity." They claim that gazing into its swirling depths can grant glimpses of infinite realities, past, present, and future, all bleeding into a maddening kaleidoscope. Some Xylan mystics believe it holds the key to transcending the limitations of their universe,a doorway to a higher plane of existence. However, most fear it - a gateway spewing forth the maddening whispers of dead universes, a corruption that unravels the mind and soul.
