Your party has fallen. On the bright side, achievement unlocked. Yes, this means the bad guy is probably going to get his way, unless the siblings of the fallen party come together and band to avenge them. Either way, your party learned a valuable lesson they probably won't remember, but, this patch, will be a mark of honor upon yourself and your fellow players. Or this may be a reminder that you, the DM, have officially led a session that ended in calamity and un-aliving your entire party. This patch is your scouts badge of dungeoneering.
