Can't get back through darkness -

[user452]

You're not completely screwed, but if i were you, I would definitely look up a map to see which direction you're supposed to be going.

I did  a similar thing, with a combination of the local wildlife, and luck.
I made it all the way to the turtle in the abyss, so I was able to ride that back to the light.

Yes but the transport turtle has a good many hungry fiends near it. If I were u id use the map and simply swim up till you break the darkness. I got into your situation my first play through and rapid fleeing works wonders.

dont worry once i got to the abyss without saving for a long time and was forced to save without

sun form too
