This can be used for making friends with a nation you're at war with, and can be a cheaper alternative to a peace offering that's normally millions of Sporebucks. However, any empires above a relationship of two are unaffected. It shares the same icon as the Siren Song ability from Creature Stage. Firing any weapon immediately ends the effect. You could use this to get one antimatter bomb or one planet buster onto an enemy planet, but you'd then lose the effect and have to wait for it to recharge again. Leaving the planet once it is activated will still allow the device to run for its duration of two minutes, preventing the other empire from attacking your spaceship as it passes.
