Remnants of the Aether
This black diamond artifact was what the Lith’gha had been searching for. It’s power, though faint, was clearly able to repel The Aether surrounding it. The Lith’gha were able to detect this and decided it to be a priority to retrieve this object and study it.
The Yahirono Himorogi was discovered by the party in the cavern-like depths of the Tower of Mokoi, although Gaiorgos and his band of travelers took it, forcefully, from the group the moment they found it.
