Knight Family Curse

A true "curse" of the Knight Family specifically is never mentioned throughout the Gabriel Knight series, but it is heavily implied through conversations.

Manifestation

 * The line of the Knight Family is relatively short with only three generations; yet three people already fell victim to the curse. Harrison Knight, Philip Knight and Margaret Templeton Knight.
 * All of them died under mysterious/unexplained circumstances when their child was eight years old. Harrison was hit by a street car; Philip and Margaret died in a car accident.
 * In case of Philip, police thought he had veered off the street to evade a wild animal. It could be speculated that Harrison also tried to flee from some unseen evil and ran in front of said street car in a panic.
 * The "old nightmares" all members of the Ritter Family suffer don't seem to be a part of the curse and more related to the fact that the Ritter Talisman had been lost to Tetelo in 1693.

Origin
It seems to have started when Heinz Ritter left Germany in the 1920s and changed his name to Harrison Knight, effectively abandoning his duty as Schattenjäger. It could be seen as a punishment for turning his back on the sacred duty of the Ritters.

Trivia
Wolfgang Ritter, Harrison's brother, and Wilhelm, his father, both seem unaffected by this specific "curse". Wilhelm had two sons and lived long enough to take the family picture Gabriel can find in the German Clock in Rebecca Knight's attic. Wolfgang lost his only child in infancy (and presumably his wife) and reached a very old age.
