Once one of the greatest of the soothsayers, this tall, burly, curly-haired man was stricken stightless because, pruely by accident, he happened upon the beautiful pseudo-goddess Athena in her bath. Athena took away his physical sight, but tried to make things better for the innocent man by giving the gift of seeing the future. Upon his death, he was sentenced to eternity in Hades.

It was Tiresias who revealed to Glorian of the Knowledge that Mirakles of the Elastic Tendon could be found on the Plain of Endless Conflict and that Charon required an obolus from each of them to cross the Acheron.
