Titus's resistance

[Zixinus]

Why is Titus resistant to the Warp?

I know that there was some kind of big story behind it for sequels that never happened, but it wasn't explained. I've learned more about W40k lore but I still struggle to find an explenation that fits with it.

It can't be because he's a pariah/null because that would have been detected during his transformation to being a Space Marine. Not to mention noticed among Librarians in his chapter. It can't be because he's a psyker for the same reason either. You'd only be resistant to the Warp if you got training.

The only explenation that kind of makes sense is that he simply has the Emperor's favor and is able to channel that like the Soritas do. It would explain his Fury abilitiy. Which is unheard (I think) of but it doesn't require much beyond absolute faith, which Titus has. So he is favored by a Warp God, but not a Chaos God. With the

The other is that he IS favoured by one of the four Warp Gods or some other obscure entity of similar power. But he'd know about it to some extent and it would show.

Finally, the other explenation is that he wasn't special until he got the Power Source. Maybe a C'tan shard or something similar? Maybe some artifact of the Old Ones?

You're digging too deep with the C'tan and Old Ones stuff, mate.
Space marines generally don't share, or even approve of, the cult of the God-Emperor. To the majority of them, the Emperor is just a human (although still the greatest human to have ever lived). So the explanation for "God-Emperor's Avatar" gets busted as well.
However, there's a story about a chapter master that got his pariah powers much after becoming a proper space marine, I think it was in the fluff of one of the less developed Imperial Fists successor chapters. So that or an innate increased resistance to the Warp are the most plausible explanations IMO.

[Zixinus]

So the better theory is reference to fluff you can't name?

Yes, the Astartes are one of the few institutions where the Imperial Cult has not spread but faith in the Emperor does not require to think of him as a god. After all, the Emperor already has billions of people to do that. Titus has faith in the Emperor too and maybe that is enough.

The idea that the Power Source is some sort of Old Ones artifact actually comes from the Ciaphas Cain novel where there was also an artifact that had had a strong effect on the Warp. That one however made latent psykers active rather than the other way around.

Titus is a demon/alien of some sort from another universe

Zixinus, look up the Sons of Dorn lore. No offense towards your other theories, but they seem rather far-fetched.

[Zixinus]

The game is very ambigous and we have little to go on, so there is little choice but going far-fetched. The fact that we never learned what the Power Source actually was is a big problem.

Alexandro's blank status is interesting. When I first finished playing Space Marine I also thought it was that a simple theory that he was a Blank somehow. I do admit that is the most simple theory but again: how come none of his chapter Librarians and other psychics did not notice that?

I still think "Emperor's blessing" is still relatively simple as it would explain the in-game Fury ability that is unique to Titus.

[Lemartes]

There are people, so rare even the Emperor did not know about them, known as incorruptables, whose unassailable will allowed them to cast possessing daemons out of their body.
But even without the unheard of immunity to the corruption of the warp through willpower, there's plenty of examples of people using willpower (if not contempt) to deny the witch.
Simplest explination-- Titus is just atypical and has a supremely strong willpower.

[SpVg Sacknaht Bielefeld]

Classic ominous plot device that has never been explained properly.
He needed to be that resilient to make the story work, thats is pretty much it.
Whether it is realistic or not is a whole different thing.

Well, I did leave the possibility for exceptions.

It's raw Warp energy, the inquisitor dude maybe even captured a lesser daemon. In short, it's space magic. It just works.

Well, as the lore of Sons of Dorn states, Alexandros the Blind got his Pariah powers after certain events came to pass. Perhaps the combination of strong willpower and being exposed to the Power Source did the same for Titus.

I would refrain from trying to explain game mechanics with lore reasons. It makes little sense to have so many power axes and thunder hammers lying around, even on a Forge world. Also, Titus being able to wield a lascannon without having devastator equipment is quite lore-breaking.
