Star Compass

The Star Compass is an Artifact found in the 1st Layer by Riko, who also named it.

Description
The Star Compass is a light blue transparent orb with patterns on its surface. It has a structure inside of it and a metal ring around it. While the grade of this artifact remains unknown, it is estimated by Riko to be a Fourth Grade Artifact.

While the ring around it floats, and maintains the same position as the globe, the structure inside the compass doesn't tilt or rotate. It maintains the same position even if the exterior body is moved.

Riko illegally took it back to Belchero Orphanage with her as her own personal item instead of turning it in for money. The needle inside it always points downwards, no matter how much you turn and shake it. Riko claims it points to the bottom of the Abyss.

Riko took it on her journey, but quickly lost it on the 1st layer when she got excited and it slipped out of her hand while she was shaking it. It hasn't been seen since.

Vueko inherited one from her caretaker, and then used it to traverse the sea to find the Abyss with Ganja. She gave it to the Abyss Tribe in an exchange for aid.

Riko's theory that it points to the bottom is backed up by the fact that while in the hands of Vueko, it always pointed towards the Abyss; even when she was far away from it.

Trivia

 * The name of the Compass was inspired by the trading card game, Magic: the Gathering.
 * The Star Compass Vueko had differs slightly from Riko's by having a less round shaped part, which goes into a cone shaped ending part for the structure inside it, while the structure inside Riko's Compass ends in anchor-shaped ending part.
 * The elderly tribesman Vueko gave the compass to points out that it is shaped in the "form of the essential part".
 * Even though we see Riko was the one to name it Star Compass, Wazukyan also refers to it as Star Compass in his initial travels.
 * The Beyond Glyph meaning "Big Pit" shown by the elderly tribesman depicts a symbol similar in shape to the Star Compass.
 * Vueko traded the Star Compass to the elder tribesman which in time was dug up by Riko and then dropped down the waterfall, confirming that Riko and Vueko shared the same Star Compass.
