A term given to any level in any video game that comes the fuck out of nowhere, is never spoken of again, and is designed to be nothing but
nightmare fodder.
Named for the ridiculously hellish zombie level of
Half Life 2, Ravenholms are those levels in video games that you will see
in your dreams.
Muahahahahahahahahahaha
The bottom of the well in
Ocarina of Time is
that game's Ravenholm. Many thousands of children were forever
scarred from it.
