Cancelled Saturn releaseBlood Omen: Legacy of Kain was to also be on the Sega Saturn.
Character namesSome of the Characters underwent name changes before the game was finished. Ariel was first called Adonathiel and Moebius was named Bridenal. Vorador's name was briefly changed to Infernum, but it was changed back.
Although it has never been stated officially, it's possible that Nosgoth is derived from Nosferatu, another name for vampires, and Goth or Gothic.
Chess sequenceOne of the most important gameplay sequence that was cut in Blood Omen was the chess sequence that Vorador would have used to challenge Kain. In the words of the Silicon Knights themselves:
The chess match was a board with real people on it, which Vorador had set up to challenge Kain. Kain had to figure out which piece to move using the Control Mind spell, and, if he made a mistake, the pieces would come to life and attack him. The correct move was a classic chess checkmate
The sequence was cut because it was not working very well and the development cycle was nearing the end.
CutscenesOriginally, there was an FMV depicting Kain's murder. It was supposed to be part of the opening cinematics tell the story of how Kain becomes a Vampire.
GraveyardFirst, find the blood script in the mausoleum. Copy the symbols down on paper.
Go to the graveyard outside. Read the gravestones. Get your paper and pen ready and waste one hour of your time deciphering the code.
The symbols each represent the corresponding letters of the alphabet omitting the letters K, Q, and W.
You then can "read" the gravestones to see the names of some of the games' developers.
LegacyThe game's plot is actually the centerpiece of what in the sequels develops into an intricate vampire-time-travel-drama. Events from Blood Omen are constantly referred to in the following games, for example, the vampire Janos Audron, who is never encountered in Blood Omen and whose backstory merely adds flavour to a power-up, becomes a character of major importance in almost all sequels.
Lightning spell caveUsing the alphabet from the Nosgoth's Blood Script, you can translate the writing at the Lightning Spell cave. It says: "He will come when the moon is full and learn to call death from the sky".
TitleBlood Omen was originally going to be called "The Pillars of Nosgoth", due to the importance of the Pillars to the storyline.
