"Blood Reaver" is the LOK fans' name given to the Reaver sword that doesn't yet have Raziel's soul inside of it.
Franchise Killer: After the first three games did very strong, Blood Omen 2 got average reviews, and to fans of the series its story and design aesthetic were a complete departure from the rest of the franchise. The series stumbled on to Defiance, which got a bit better reception on both fronts, but it wasn't enough to save the series.
Simon Templeman is getting around the videogame scene as of late; even when Defiance was new, he wasn't in many other titles, and was usually just a random bit part when he was in something else. It can be jarring for anyone who played this series to hear him these days, particularly as Loghain in Dragon Age: Origins, where he's doing the "Kain Voice" on a character with a lot of screen time.note Simon Templeman is primarily a theatre actor.
Their voices aren't particularly alike, but if you're aware of it you can hear the similarities: Ariel is voiced by Skylar White, of all people.
One of Us: Hilariously inverted; in the behind-the-scenes feature for Soul Reaver 2, Michael Bell tells of how he had to actually buy a Playstation when Crystal Dynamics sent him a free copy of Soul Reaver. He was eager to see the entire game because of how he imagined it would turn out from the script, and because he used his talent for multiple voices to cover several characters. Being a non-gamer, he couldn't handle the platforming at all and spent two hours trying (and failing) to pass the platforming portion of the tutorial, only for his daughter to be so far beyond it the scene was unrecognizable when he came back from getting a beer out of the fridge.
The Other Darrin: Mortanius was initially voiced by Tony Jay in Blood Omen, leading to some Wild Mass Guessing regarding the Elder God's identity when Jay went on to voice that character instead. His actor was changed in Defiance, to avoid confusion.
Serendipity Writes the Plot: Turel was supposed to be included in Soul Reaver, Dummied Out locations and dialogue make it clear that Raziel would have eventually gone after him. However, the team was out of time so Turel was cut without mention, and later games made his absence from Soul Reaver a plot point.
Talking to Himself - Michael Bell, Raziel's voice actor, also played Melchiah and various antagonists. Taken to its logical extreme when Raziel confronts his past self.
What Could Have Been - A project called Legacy of Kain: Dead Sun would've focused on the future of Nosgoth resulting from the end of Defiance, starring a human whose soul (through some freak accident) winds up in control of the vampire that kills him. Unfortunately, Square Enix cancelled it in 2012.
