While you were out, I received a message asking for help, but the voice grew weaker and weaker.
I think someone from the Meteorite Crater sent it, but that struck me as odd, because, well, pretty much everyone there died. You should check it out. I'll stay here and, um, send you positive energy. Yeah. That's what I'll do.
I suggest you destroy the monsters near the Meteorite Crater before you go exploring... it'll make things easier for you.
