A Crossover Fusion Fic of Halo and Warhammer 40,000 written by Fan-Fiction author AzureSpider, The Hammer and the Rings features a universe that is Halo and Warhammer merged into one, leading to a world in which the Covenant aliens are servants of the Four Powers and the humans and Eldar have an Enemy Mine against them. The crossover features many altered versions of actual Halo stories, and due to the author's admitted limited knowledge of the Warhammer 40k universe he plays fast and loose with the canon of the Grim-Dark world, though the story itself is still pretty good for what it is.

. The author has also written the fan-fiction Spider-Man: Downfall.
This story contains examples of:
- Adaptational Heroism: The Eldar, who though still possessing Manipulative Bastard tendencies and some Fantastic Racism towards the humans, are not guilty of the same atrocities their mainstream counterparts are.
- In particular Eldrad Ulthran never caused an Ork Warboss who killed a billion humans to come to power here.
- The Imperium of Man also due to being fused with the UNSC
- Adaptational Villainy: The Insurrectionists, who were already pretty bad, become this world's Chaos Space Marines after willingly joining the Four Powers.
- Badass Crew: The Human's Admiralty Board, who consist of the leaders of the different Space Marine chapters.
- Bright Is Not Good: The servants of Tzeentch, who wear sky blue and pink. Averted with the colorful humans and Eldar though.
- Canon Foreigner: The Elder One, Endewan, Donald, Captain (later Colonel) Dawson, and Alexander
- Canon Immigrant: Quite a few different characters from various corners of Halo show up in this story, as well as several characters from Warhammer Dawn of War (Sindri, Bale, and Macha).
- Chainsaw Good: The Chaos Space Marines here retain their chainsaw swords though also seem to be the only humans that do.
- Crapsack World: The original Warhammer 40k universe, hence why the Elder fused it with the Halo Universe.
- Dark Is Evil: The servants of Chaos Undivided (including the Chaos Space Marines) wear black armor.
- Death by Adaptation: Thomas Lasky, who here dies in place of Chyler Silva during the Covenant's attack on Corbulo
- Fire-Breathing Weapon: Here the Hunter's cannons shoot Eldritch Flames instead of Fuel Rod blasts due to their devotion to Tzeentch.
- Foreshadowing: Chapter 7 features what Eldrad identifies as disintegration weapons, suggesting the Necrons. Lo and behold, the Necrons do indeed show up soon after.
- Good Is Not Nice: The Eldar, who don't think highly of humanity and don't even try to hide or moderate their racist opinions of them. But at the same time the Eldar are also working tirelessly to stop the Four Powers and the Covenant.
- Helmets Are Hardly Heroic: Inverted by and large. The humans and Eldar mostly wear full-face covering helmets in battle while the only villains to wear helmets are the Elites, Chaos Space Marines, and Dark Eldar.
- Hopeless War: What the Eldar's war with the Covenant is starting to look like, hence why they form an alliance with humanity.
- Interservice Rivalry: Between the servants of the different Four Powers. Also mildly between the humans and Eldar.
- Knight in Sour Armor: Quite a few of the humans are this, especially the Admiralty Board.
- Lighter and Softer: Invoked in-universe. The Elder One fused the Warhammer 40k world with the Halo universe precisely so a better world could be created. Though in the case of the Halo half, this fan-fiction's tone is pretty on point.
- The Mole: According to Sindri, he has a spy on the inside.
- Psychic Powers: Many of the Eldar have these, with the Farseers and in particular Eldrad Ulthran having perfected the ability. Unfortunately though they cannot read the minds of servants of Chaos for too long lest they become corrupted by Chaos as well.
- Retcon: Quite a few, not the least of which being Fulgrim being an Eldar instead of a Primarch and the Chaos Space Marines being Insurrectionists who have willingly joined the Four Powers.
- Shock and Awe: The Eldar Farseers and Lord of Change are both capable of discharging powerful blasts of electricity.
- Spared by the Adaptation: Chyler Silva and Dimah Tchavoka in the Corbulo chapter. Subverted with Junjie Chen, who lives a little longer but ultimately dies anyway.
- Teeth-Clenched Teamwork: Villainous example. Lord Bale and the Arbiter hate Sindri due to his being 1: A human, 2: A servant of Tzeentch (they're both servants of Khorne at heart), and 3: Preferring Pragmatic Villainy.
- Winged Humanoid: Bahharoth and his Swooping Hawks, as well as the Lord of Change.
