Tablet X

Gilgamesh finally arrived to where he wanted to be, but the tavern keeper refuses to open the door for him because he looks like he's been on a journey and has a bitter face (a phrase that is repeated about, oh, five thousand times this chapter).

But at least she tells him where he can find someone who will tell him where the person he is seeking for is, which is on an island in the sea where there's no possible way Gilgamesh can find him.

But he does, and that guy that tells him where he can find the Guy-With-Such-a-Weird-Name-He -Became-Immortal-To-Learn-It (which is in Faraway. What an original name!), and they set off together, across the waters of death, to another island where the immortal man is.

The man actually says something pretty interesting there, which is (in metaphor) that nothing can last forever and all humans die, whether they be peasant or king, and that the day of death is set at birth, though it isn't known.
