A Guiding Star Gem is a small, mystical gemstone that has the power to teleport a person from one place to another.
Guardian Knuckles the Echidna was given one by his great-grandfather Athair through his friend Yanar, as he knew that once Knuckles completed his destined journey to return the Lost Tribe of Echidnas to the Echidnas' original city of Albion, that he would not want to remain with them and would want to return to his friends on the Floating Island instead. (KtE: #10, #11, #12)
- When asked why Knuckles no longer used the Guiding Star Gem, writer Ian Flynn stated "He dropped it when he got mugged by the Destructix. Also, we're phasing that out in favor of the much easier to show/explain Warp Rings. Also, Knuckles just got done causing all kinds of havoc with his Chaos power - I doubt he's eager to use it right now for anything. He made a big step in #186, but he still has issues over being Enerjak."
