Trope-a-Day: Battle Aura

Battle Aura: Not really a battle aura – since it’s hardly restricted to military situations (see: Mundane Utility), but those implanted effectors used for mechanical psychokinesis do, under the right circumstances, bleed off excess energy in the form of photons, in turn in the form of nice light shows.

Which can be both convenient and inconvenient (needing to keep that energy somewhere else when sneaking, for example), and which quite a few people learn to trigger even when they’re not about to lay some psychokinesis on something, just to show off.¬† Or intimidate.
