What was the end outcome for Gilgamesh in The Epic of Gilgamesh? Did he spend time in the afterlife where his friend was?

What happens to
Gilgamesh after his death is
not elaborated upon in this epic text. The reader merely witnesses
the lament
to Gilgamesh and the way that everybody--gods included--mourn his passing.
However,
looking back at the text, it is clear that the mortality of man is
one of its principle themes,
and it does in places explore the afterlife and
what happens to those who die. Note, for
example, the following
reference:

The common man, the
noble
man,

Once they have reached the end of life,

Are
all
gathered in as one,

By Anunnaki, the Great
Gods...

This quote is of course a
reference to death as a force of
equality, who does not respect class, rank
or status. However, note too the indication of what
happens to people when
they die. The phrase "gathered in as one" does seem to point to
some kind of
reunification in the afterlife. Thus it can be safely concluded that Gilgamesh
in
death is finally reunited with his beloved Endiku. This is something
however that the reader is
left to surmise from the text: there is no
description at the end of this epic classic of what
happens to Gilgamesh
after his death. In a sense, the main theme of this text is the mortality
of
man and that all humans, however mighty, must die and have limited days. This of
course
supports one of the main messages of this text: being limited in our
mortality as humans, we
must therefore consider very carefully how we live
the days we have.
