Prometheus has a lot of feelings about the Eagle that comes to torture him every day. But when that eagle lands, broken, on his mountain, Prometheus doesn't know what to do (and it's not like he can do anything).The eagle can't even turn back into an eagle - stuck in his human shape, unable to leave, he tells his story - in exchange for one of Prometheus'.There's a lot to say, but dredging up the past is difficult.
