Mark of the Overmind

Not much is known about these diminutive drones. What is known, however, is that they assign themselves to beings of considerable value; Political leaders, admirals, priests etc. And remain by their side until they complete some unspecified objective. Attempts to destroy them both through conventional and magical means have failed, as they seem to actively break causality as a defensive measure; Guns jam, spells miscast or the caster gets brain fog, IFF systems stutter and die. Attempts to develop countermeasures are ongoing.
