In the Dead of the Night

The sun slowly sets over the land, and in the shadows terrible creatures begin to stir; crimson eyes piercing the darkness, fangs hungry for blood.  Will you cower in fear, or join them in their hunt?

or maybe even fight back.

In the Dead of the Night is a modpack themed around darkness and the vampirism mod, as well as containing a number of mods that make exploration much more interesting.  Altogether, very vanilla flavored, but still very entertaining.
