My story involves a superhuman organization that aims to overthrow the main government, through any means necessary. This involves murder and some rather gruesome deaths. Additionally, there might be accidents involving dangerous animals, magical artifacts, etc.

How do I transition dark themes into a story that isn't overly dark? My story has these dark themes, but not at the beginning and they only happen during serious and important moments. Otherwise, the characters go about their everyday business.

I'm four chapters in and nothing dark has happened. How can I transition the reader into themes of darkness or death, without completely turning them off and having them say "this isn't what I thought I was reading"?

I just want some advice for introducing dark themes to an otherwise normal story.

For example, Harry Potter gradually got darker and darker as the series went on. And even just the first book didn't have darker themes until Hagrid mentioned Voldemort for the first time.

Foreshadowing is your friend.

Your example of Harry Potter isn't quite right. Chapter One is titled The Boy Who Lived. Now that's a bit ominous. Magic is hinted at on page 1* and is outright on page 2. "You-Know-Who" is first mentioned on page 5. By page 11, when the name Voldemort is first mentioned, we already know he was a danger and now believed to be gone (but it's not certain). The chapter goes on to describe Harry's parents' deaths, that he survived, and that he was being handed over to his abusive aunt and uncle. By the end of that first chapter, we know there will be a story about good vs evil that involves the little infant who somehow survived the villain who murdered his parents.

Your book doesn't even have to be as direct as this middle-grade/young-adult series begins. Just have some strange stuff in the background. Newspaper headlines, whispers on the street, TV news reports. Make it clear that this is a world where XYZ can happen, even if it hasn't happened yet in your story.

Show us this world where magic, darkness, and death lurk around the corner. People live their lives normally in the meantime, but they know these things are possibilities. Or maybe they don't know...but they hear of strange happenings (things that happen to other people). What's important is that your reader knows they're possible. Then it won't come as a surprise.

* My pages are from the American trade paperback edition.

Four chapters in, your readers should have an idea what they're in for. Not everything that's going to happen, but certainly a hint. Once you've hinted that there is darkness, you can skirt it, turn your back on it for a while, or plunge right into it as you see fit in different parts of your story. But it can't just show up out of nowhere more than a quarter of the way through.

Yo mention Harry Potter, so I will use that as an example. Voldemort is in fact mentioned right in the first chapter, by Dumbledore and McGonagall:

'What they're saying,' she pressed on, 'is that last night Voldemort turned up in Godric's Hollow. He went to find the Potters. The rumour is that Lily and James Potter are - are - that they're - dead.'

Dumbledore bowed his head. Professor McGonagall gasped.

'Lily and James ... I can't believe it... I didn't want to believe it ... Oh, Albus ...'
_{J.K. Rowling, Harry Potter and the Philosopher's Stone, chapter 1 - The Boy Who Lived}

Death isn't going to be brushed over in this story.

'It's - it's true?' faltered Professor McGonagall. 'After all he's done ... all the people he's killed ...
_ibid

That Voldemort was a serious monster. And there's no sense of giving him this much page-time if that's the last we're going to hear of him.

After that first mention, we spend quite some time without anything "dark" happening. Hagrid mentions Voldemort and gives us more information about him when he meets Harry - we get another hint that Voldemort is important. But overall, most of the first book is "fun in magic-land". Nonetheless, there in the first chapter we saw a gun on the wall. When the gun fires, it's not out of the blue.

Every time Voldemort's attempted return is thwarted, the gun jams. But a gun that doesn't fire is boring. Eventually, the gun has got to fire, Voldemort has got to come back. In the first chapter of the first book we got a promise of darkness. Sooner or later, the promise has got to be realised. And each time the promise is repeated, our anticipation grows. So when Voldemort finally returns, there's got to be enough darkness to satisfy the promise.

That's what you've got to provide in your first chapters - a gun on the wall. Whatever your dark themes are, hint at them in the first chapters, hint some more a while later. When you need the darkness to finally show its face, you've got the gun on the wall - all you need is to take it off and pull the trigger.
