[Bêthberry]

Another thing to consider: plagues are not specifically designed weapons. They target everyone. And that would possibly include the Ring Bearer. It it had been buried with the Bearer, the Ring could have been lost in a grave with a little quick lime or, if he fell far away from civilization, in some unknown clime, blanketed by leaves and earth and perhaps prey to carrion-seeking carnivores. Like the River, the earth would give the Ring a quiet bearth where none would find it. Until upheaval, of course. And that possibility may be a little too long term even for someone with eons of time at his disposal.
