The Battle of Killahead Bridge was a great battle where Gunmar and his followers were banished to the Darklands by one of the mightiest Trollhunters in Troll history, Deya the Deliverer.

The second Battle of Killahead Bridge was where the first human Trollhunter, Jim Lake Jr., fights against Gunmar's son, Bular, to prevent him from releasing Gunmar from the Darklands.


First Battle of Killahead

This event prior to the events of Trollhunters. The exact date and year is unknown, but it happened centuries ago and after Angor Rot asked for help from Morgana as he was trying to defend his tribe from Gunmar.

The battle took place between the Gumm-Gumm army led by Gunmar, who was trying to take control of the surface, and several other Trolls who opposed them, led by the Trollhunter, Deya. The battle reach its close when Deya puts the Amulet of Daylight in the Killahead Bridge and banished Gunmar and all the Gumm-Gumms (except for Bular) into the Darklands.

Unbeknownst to the trolls during the battle, Merlin and Morgana engaged in an epic duel for the fate of the world. Merlin successfully triumphs over Morgana, using up most of his magic to banish her by confining her in a prison within a Heartstone underneath what would later be called Arcadia Oaks.

After Deya banished Gunmar, she instructed the trolls to tear up the Killahead Bridge stone-by-stone and sent the pieces to the farthest corners of the world.

Second Battle of Killahead

Centuries after the battle, the Killahead Bridge was reconstructed by Bular, along with the Janus Order, in order to free Gunmar and the Gumm-Gumms from the Darklands. They managed to steal the Amulet of Daylight, but everyone later discovered that only the Trollhunter could use the amulet to open the bridge.

The Changelings kidnap Blinky, the mentor of the new Trollhunter, Jim Lake Jr., in order to force him to open the bridge. Although this at the beginning, it turned out Jim managed to alert his allies of his whereabouts and thus unleash a battle against Bular, the changelings, and goblins.

At the height of the battle, Stricklander successfully as able to open the bridge. However, Draal manages to pull out the amulet in the last minute, resulting in the bridge being destroyed at cost of Draal's arm.


Almost all troll tribes took part in the first battle, including Morgana and Merlin (unknowingly to the trolls).
