For a few millenia,
here i've been chained,
forced to obey,
as the laws of time,
bind me.
So here I wait,
for my release,
as to start the end of days,
and bring forth my hatred.
The snow is blinding,
the ice is numbingly cold,
but these chains burn my wrists.
I howl with pain,
as I am lonely,
I cannot eat,
I cannot sleep,
I just wait,
because one day,
they will slip,
and i'll be there,
to rain down my terror.
