DOOM: The Dark Ages Complete Lore & Story Guide: Timeline, Characters & Connection to DOOM 2016
DOOM: TDA is a prequel set between DOOM 64 and DOOM 2016. It explains how the Slayer ended up in that sarcophagus at the start of DOOM 2016 and why the Maykrs and Hell are so afraid of him. The story is mostly told through codex entries and environmental details rather than cutscenes, so it is easy to miss the full picture. Here is everything.
The Timeline: Where TDA Fits
The DOOM timeline: DOOM (1993) → DOOM II → DOOM 64 → DOOM: The Dark Ages → DOOM 2016 → DOOM Eternal → DOOM Eternal: The Ancient Gods.
After the events of DOOM 64, the Slayer stayed in Hell to fight demons forever. Over eons of endless combat, he became something more than human — a demigod fueled by rage and the souls of the demons he killed. The Maykrs, an advanced civilization from the dimension of Urdak, discovered the Slayer and saw him as a weapon they could use.
The Maykrs And The Tether
The Maykrs, led by the Khan Maykr, offered the Slayer a deal: serve as their champion against Hell, and they would give him purpose, weapons, and armor. The Slayer agreed. The Maykrs embedded a device called the Tether into the Slayer's armor — it gave him enhanced abilities (the dash, the shield saw, the weapon wheel mechanics) but also allowed the Maykrs to control where and when he deployed.
The Tether is the in-universe explanation for your HUD, your weapon switching, and your ability to carry an arsenal in hammer space. It is also the explanation for mission select and checkpoint restarting — the Maykrs are literally deploying and redeploying you.
The Betrayal: During the events of TDA, the Slayer discovers that the Maykrs are not fighting Hell — they are managing it. Hell produces Argent Energy, which the Maykrs harvest to power Urdak. The endless war is a farming operation. The Slayer is an unknowing participant in a system designed to keep Hell productive.
The moment the Slayer discovers this, he turns on the Maykrs. The final third of the game is the Slayer fighting through Maykr forces in addition to demons. The Tether becomes a liability — the Maykrs can track him, disable his weapons, and even trigger his armor's pain receptors.
The Wraiths And The Divinity Machine
The Wraiths are ancient beings native to Argent D'Nur, a world that Hell conquered and absorbed. The Wraiths created the Divinity Machine — a device that can infuse a mortal with divine power. The Slayer was put through the Divinity Machine by a renegade Maykr named Samur (who you meet in TDA). This is what transformed the Slayer from a very angry Marine into a demigod who can punch a Baron of Hell to death.
The three Wraiths — the Gladiator, the Beast, and the Seer — each grant the Slayer a portion of their power during the game. The Gladiator gives strength (melee damage buff), the Beast gives rage (Berserk power-up duration extension), and the Seer gives clarity (ability to see hidden paths and secrets).
Samur is the same Samur Maykr who appears in DOOM Eternal as Samuel Hayden's original identity. TDA shows Samur before his transformation into a human-like android. He is the only Maykr who opposes the Khan Maykr's plan, and his defection sets up the events of Eternal.
The Icon Of Sin And The Sealing
The final boss of TDA is the Icon of Sin — the same titan you fight in DOOM Eternal, but at full power before the Slayer weakened it. The Slayer defeats it using the Atlan Mech and Mecha Dragon, but cannot permanently kill it. Instead, Samur helps the Slayer seal the Icon beneath the surface of Mars (where you later fight it in DOOM Eternal).
After the Icon is sealed, the Maykrs turn on the Slayer fully. The Khan Maykr orders his capture. In the final cutscene, the Slayer is overwhelmed by Maykr forces, stripped of his Tether, and placed in a sarcophagus — the same sarcophagus you wake up in at the start of DOOM 2016.
The Tether remains with the Maykrs, which is why the Slayer in DOOM 2016 has a much simpler HUD and weapon system — he has no Tether anymore. His armor in 2016 is a new suit (the Praetor Suit), not the Tether armor from TDA.
Key Characters
The Slayer: The protagonist. More talkative than in 2016/Eternal — he actually speaks a few lines in TDA, mostly to Samur and the Wraiths. His personality is less pure rage and more grim determination. He has been fighting for eons and it shows.
Samur Maykr: The renegade Maykr who believes the War against Hell should be genuine, not a farming operation. He becomes the Slayer's ally and ultimately sacrifices his Maykr form to save the Slayer, leading to his transformation into Samuel Hayden.
The Khan Maykr: The primary antagonist. Appears in TDA as a holographic presence, not a direct combatant. Her betrayal of the Slayer is the emotional core of the story. She genuinely believes she is doing what is necessary for Urdak's survival.
The Wraiths: Three ancient beings who empower the Slayer. Each has a distinct personality — the Gladiator is honorable, the Beast is feral, the Seer is cryptic. They view the Slayer as a worthy champion rather than a tool.
Valen (the Betrayer): Appears in flashbacks. His son was turned into the Icon of Sin by Hell priests, which drove him to betray Argent D'Nur. You see his son's transformation in a story mission, which is one of the most disturbing sequences in the franchise.
Connection To DOOM 2016
The ending of TDA leads directly into the beginning of DOOM 2016. The sarcophagus you wake up in during 2016's opening is the same sarcophagus the Maykrs place the Slayer in at the end of TDA. The UAC facility on Mars in 2016 was built around the sarcophagus after it was discovered by archaeologists.
Olivia Pierce, the villain of DOOM 2016, is directly exploiting the Argent Energy infrastructure that the Maykrs established during the TDA era. The entire Hell energy operation in 2016 is a degraded, human-discovered version of the Maykr-Hell farming system.
Samuel Hayden in 2016 is Samur Maykr after centuries of degradation. He has forgotten his own history. The mystery of why Hayden knows so much about Hell and the Slayer is answered here — he lived through it all as Samur.
