@Polybius works though in this case I need to inform you that magic will be in need ot be kept in check at this setting. tunnels and caverns aren't exactly the most stable of surroundings so any big explosion or aoe could decimate your allies instead xD ^^ Also in this case later if this gets off hte ground before we start I will Pm you some of the dangers out there ^^
Of course, I'm more interested in building character and setting than blowing things up!
