As a bridge between the surface world and the Darklands, the Killahead Bridge was a place of great historical significance. The bridge was the frontline of the last great battle between the Good Trolls and the evil Gumm-Gumms.
The Art of Trollhunters

The Killahead Bridge is a magical stone bridge that acts as the portal to the Darklands.

It once served as a border between Camelot and the Wild Wood, until King Arthur's demise and Gunmar's exile during the Battle of Killahead Bridge. After which, the trolls tore the bridge into pieces and hid them across the world to ensure the Gumm-Gumms would never return. However, Gunmar's son, Bular, plotted with the Changelings of the Janus Order to find all of the pieces and free his father.


In the Dark Ages, Killahead was the border between Camelot (human domain) and the Wild Wood (magic domain). However, after King Arthur sent out his hunting party across the bridge to slay the trolls who escaped his captivity, Gunmar retaliated by declaring war over the innocents (including the innocent trolls of Dwoza). After Gunmar raided villages and recruited trolls in his army by force, Arthur took in half of his army to the dry river which Killahead overlooked. After the sun sets, the legendary Battle of Killahead Bridge begins. When the Knights of Camelot begin to triumph over the Gumm-Gumms, Morgana and the Arcane Order intervene and allowed Gunmar to weaken the knights by assassinating their king themselves and tear down Killahead.

Luckily, the good trolls of Dwoza arrive with Deya the Deliverer, the first Trollhunter, leading them into battle. Merlin manages to imprison Morgana due to her fall into dark magics, and locked her body in a Heartstone under what would be called Arcadia Oaks in the future. Meanwhile, Deya blinds Bellroc into retreating, along with the rest of the Arcane Order, before she confronts Gunmar on the bridge. After a large spar, Deya uses the Amulet of Daylight to exile and imprison Gunmar and his army into the Darklands, and sealed it so they could never escape.

In the aftermath of the battle, the bridge was then destroyed into pieces and its remains were scattered all over the world. Camelot is taken into the air, thanks to the Heart of Avalon, and lost in legends by humans, and the trolls relocate to the New World in search of a new Heartstone and safe haven.

Centuries later, the son of Gunmar, Bular, and the Changelings began to gather the stones of the bridge to be able to reconstruct it and thus release Gunmar. However, the portal could only be opened by the Amulet and by the hand of the Trollhunter. They manage to force the current Trollhunter, Jim Lake, to open the portal. However, Draal manages to remove the Amulet from the bridge before Gunmar could be released, losing his arm in the process.

The remains of the bridge were then moved and guarded within a vault inside Trollmarket, until Jim decides to leave alone to the Darklands to destroy Gunmar. Having assembled all three Triumbric Stones and unlocked the Eclipse Blade, the only weapon capable of mortally wounding Gunmar, he uses the Amulet to rebuild the bridge and cross to the Darklands.

When the Queen Usurna orders the bridge to be destroyed to prevent Gunmar from escaping, Jim's friends try to stop them, but they can not prevent the bridge from being destroyed once more, leaving Jim trapped in the Darklands, with Enrique being the only one who manages to escape. The remains of the bridge are sent in a cargo truck and launched into the ocean. However, Claire and NotEnrique manage to use the Shadow Staff to recover all the remains of the bridge. When the spirit of the previous Trollhunter, Kanjigar, possesses AAARRRGGHH!!!, he uses the amulet to repair and open the bridge once again, allowing the group to rescue Jim and Nomura from the Darklands. However, unknowingly to the Trollhunters before the bridge was closed again, Gunmar manages to escape, along with two of his soldiers, Dictatious, and some Blood Goblins.

The Trollhunters later disposed of the bridge, though the whereabouts of where they disposed of the pieces remains unknown.


It was a large stone bridge with elaborate carvings on it, mostly events of Gumm-Gumm history (one of these carvings depicted Gunmar and Orlagk's battle). The bridge had a circular depression on its apex, designed to house the Amulet of Daylight.


The Killahead Bridge is the only known main way to enter/exit the Darklands (with the exception of Fetches, which are mere "cracks" that allow only small things to pass, as described by Blinky).


Even if the bridge is torn apart piece-by-piece, it cannot be destroyed permanently, but only disposed of.

Also, only the Trollhunter can open the Killahead Bridge and reassemble it simultaneously with the Amulet of Daylight.

  • In the 2015 book, the bridge was called the "Killaheed Bridge". Jim Sturges once mispronounced the bridge as "Killahead".
    • The name is also diverted from the phrase "Kill ahead", lampshaded by Callista as a "scary name for such a puny bridge".
