The Sol "Erinyes" needs to use these in order to get you right where it wants you
It seduces you into selling your soul to the-- Oh... Not that kind of Erinyes...
Given Bobboau's hint, it sounds like the Sol-Terran's version of the Trebuchet. Earthlings need fish too, right?
Given Ace's hint, it sounds like it kicks the crap out of your shields and subsystems, possibly carrying an EMP effect to go with the damage. That would leave you disoriented and vulnerable to primary fire, especially if it knocks out your engines or weapons. This could be fun, as long as I remember not to catch myself in the blast (kind of why I don't carry EMP weapons much to begin with).
