This just in from the ENWorld review: "The famous occult detective Alanik Ray and adventuring physician Arthur Sedgwick are an example of how they're updated. While pursuing a serial killer Alanik fell from a roof, paralyzing his legs. Since his intellect has always been his greatest weapon, he still solves mysteries from a custom wheelchair, aided by Sedgwick, who he married."
All right, I have officially changed my position on what I will do if I get one use of a time travel machine to change history.
Rather than go back to 1836 and arrange, somehow, for Karl Marx not to get expelled from the University of Bonn (thus preventing him from attending the University of Berlin where he would get involved with Feuerbach and the Young Hegelians, which led directly to the spawning of Marxism which has a direct causal root of all the atrocities of the 20th century), I will go back in time to 1963, when Star Trek is being developed, and persuade Gene Roddenberry to give Mr. Spock a wife as a key running character in the show. This will hopefully nip in the bud the entire phenomenon of K/S fanfic, from which I believe all this kind of sexual-reinvention character shenanigans first developed. (Seriously, when did genre fandom become convinced that any kind of close emotional relationship automatically read as a potentially sexual one?)
Roddenberry himself personally quashed this nonsense when he wrote the novelization to star trek the motion picture. In the preface written by admiral kirk, he refuted these claims completely and pointed out that even he he were so inclined he would not be foolish enough to pick a partner who only became sexually aroused once every 7 years.
Oh, and marxism was an inevitable result of the horrific conditions the russian population was suffering under the czars. If you really wanted to prevent the marxist revolution which would have happened under a different name if you neutralized marx, you need to go back in time and adduct the czar, then show him what was going to happen to him and his family, including sadly poor Anastasia despite a lot of wishful thinking, and tell him to make real serious reforms in how the people were treated. Nothing else would have stopped a populist revolt in russia, period.
Here, check out this two part video, it's very concise, informative and entertaining.
