Oddly glowing rock containing a significant amount of mana.
A proficient mage can absorb the mana directly from the stone after a long meditation.
NOTE:
The mana glowstone was discovered on a riverbed near the town by an adventurer named Ryzen.
A map of the surface-level vein has been submitted by Lily.
Adventurer Nyx noted that the vein contains low graded mana glowstone.
