I suspected it might be a trap and I jumped in anyway. I barely survived. I think these are supposed to be the FROM version of Sirens?Those damn Italian bats. Are they gonna kill you or make you a nice spagetti?
Just kidding they gonna kill you.
I mean, with these games sometimes the nice dude is just waiting to shove a knife into your back and the big scary dude is amicable enough. In this case, the scary looking bats singing opera are just trying to lure you in to gank you. Too bad because I would have liked to attend their concert. I would have given them some runes as a donation if they had not tried to kill me. Just put a little pot there for donations. Are runes a physical thing? Or do they exist as an intangible form of credit that people have an invisible reader for? Quick, someone get Vaati on the phone! We need a lore answer, STAT!
