Stardust Bugs

The Stardust Bugs are microscopic reconnaissance organisms used by the Oak Heart clan. They are so small that they are "ten thousand times tinier than a speck of dust," which allows them to evade virtually all means of detection, including those of Morning Star mages. Originally discovered on another plane of existence and modified to turn them into probes, they constitute the clan's most secret espionage tool, capable of tracking, surveilling and transmitting detailed data on any mage to which they attach themselves.
