Eran (umm_eran)

Now that it was evening, they encamped by the river of forgetfulness, whose water no container can hold. It is necessary for all to drink a fixed amount of the water, but some do not have the wisdom to keep from drinking more than this amount. As one drinks one becomes forgetful of everything. In the middle of the night when they were asleep there was thunder and an earthquake, and then suddenly just like shooting stars they were borne upward, each in a different direction to his birth.
