I added a quick insert into the About section - tell me if that's good, or if I should really go into it a bit.
And, well, you might get a kick out of this; I wasn't even thinking about Mass Effect. I was thinking of Doctor Who and his Sonic Screwdriver that'd fix anything. And after I thought of something that'd do the trick, I asked myself if it was a waste to just limit it to only menial work, so went and weaponized it. Because it was a volumetric weapon, I was already thinking about all the ways the users could dress up their blade. One might want it to look like green translucent glass with some strands of gold in it, and another might want it to look like a red hot steel sword for an example. Now that you point out the Mass Effect though, I'm not sure what to think.
