Stardust Bugs

Stardust Bugs are microscopic surveillance organisms used by the Oakheart Clan. So small they are "ten thousand times smaller than a speck of dust," they bypass almost all detection, including that of Morning Star Magi. Originally discovered on another plane and modified into probes, they serve as the clan's most secret espionage tool, capable of tracking, observing, and transmitting detailed data about any Magus they cling to.
