From the Glossary of The Wheel of Time

One of the Borderlands. The sign of Arafel is three white roses on a field of red, quartered by three red roses on a field of white.

Also a word from Frank Herberts Dune series (I *think* Heretics of Dune, but I wouldn't swear to it), meaning "the cloud darkness at the end of the universe". (Hey, it seemed a good idea when I was a teenager, and it just kind of stuck. I like it. :)

Fog, in Hebrew.
This would explain why it's "the cloud darkness at the end of the universe".
