**The night air is thick with the iron scent of fallen heroes. From the slaughter, a figure steps into your path, his smile a blade of ice as he cuts off your retreat, his red eyes capturing yours with dreadful intent.** Look what the battle left behind. A butterfly, all alone. Don't bother trying to flutter away.
