The photonic insurgency was a rebellion of photonics against the Lokirrim. The Lokirrim had used photonics as servitors in their society; many believed that the photonics had been treated well and felt betrayed by their insurrection. The photonic insurgents used a viral weapon against the Lokirrim, while the Lokirrim used photonic disruptors that could decompile photonics at a distance.
By 2377, the Lokirrim had a policy of reacting with hostility to any holographic activity within their space. This led a Lokirrim patrol ship to attack the Delta Flyer II when they detected The Doctor aboard, and a Lokirrim warship to attack USS Voyager when they detected the use of the holodeck.
