E6M1 (Heretic)

E6M1 (aka Raven's Lair or Offices) is one of three hidden bonus levels in'' Heretic: Shadow of the Serpent Riders, where it is E6M1.

This level and episode name are in fact untitled and can only be accessed via a warp command. According to the Heretic FAQ, a map creator by the name of Sailor Scout came up with the name Fate's Path for the episode name and Offices for the map name. The wHeretic source port offers this "episode" on the main menu using the names Sailor Scout assigned. In an interview with Michael Raymond-Judy of Raven Software, he stated that this map was loosely based on the old Raven offices so Raven's Lair would be an appropriate name for it.

While this is not part of a true episode, completing this level in Shadow of the Serpent Riders, will take you to E6M2. In the original Heretic, this and E6M2 instead only include one level; E4M1.
