Moongarm

Then spoke Gangleri: ‘What is the origin of the wolves?’
High said: ‘A certain giantess lives east of Midgard in a forest
called Ironwood. In that forest live trollwives called Iarnvidiur.
The ancient giantess breeds as sons many giants and all in wolf
shapes, and it is from them that these wolves are descended. And
they say that from this clan will come a most mighty one called
Moongarm. He will fill himself with the lifeblood of everyone that
dies, and he will swallow heavenly bodies and spatter heaven and
all the skies with blood. As a result the sun will lose its shine and
winds will then be violent and will rage to and fro. Thus it says in
Voluspa:

In the east lives the old one, in Ironwood, and breeds there
Fenrir’s kind. Out of them all comes one in particular, sun’s
snatcher in troll’s guise.

He gorges the life of doomed men, reddens gods’ halls with
red gore. Dark is sunshine for summers after, all weathers
hostile. Know you yet, or what?’

Then spoke Gangleri: ‘What way is there to heaven from earth?’

----------

Then something will happen that will be thought a most signifi-
cant event, the wolf will swallow the sun, and people will think
this a great disaster. Then the other wolf will catch the moon, and
he also will cause much mischief. The stars will disappear from
the sky. Then there will take place another event, the whole earth
and mountains will shake so much that trees will become up-
rooted from the earth and the mountains will fall, and all fetters
and bonds will snap and break. Then Fenriswolf will get free.
Then the ocean will surge up on to the lands because the Midgard
serpent will fly into a giant rage and make its way ashore. Then it
will also happen that Naglfar will be loosed from its moorings, the
ship of that name. It is made of dead people’s nails, and it is worth
taking care lest anyone die with untrimmed nails, since such a
person contributes much material to the ship Naglfar which gods
and men wish would take a long time to finish. And in this flood
Naglfar will be carried along. There is a giant called Hrym who
will captain Naglfar.
