Occasionally, an ettin will survive to a great age, and its heads will come to an uncomfortable final alliance. Their objective is to die, and they will rampage until a defense can be mounted against them. Such a creature is a terror to remote settlements, and even fortified castles have much to fear.
In some rare cases, a fallen ettin elder will sink into the earth. The blood it shares with stone giants causes them to petrify, leaving behind odd, head-shaped boulders sticking up from the earth. Later peoples may remember these stones as holy places and leave offerings to the memories of these long-forgotten monsters.
