Under unknown circumstances, Kartag became a servant of the Norns/Fates. For 200,000 years, Kartag guarded the cave to the Twilight Well at World's End. In that time, none had ever crossed its threshold and lived.

On the verge of an assault by Mangog, Odin dispatched Thor and the Warriors Three to wrest the secret of the Twilight Well from Kartag. The four faced numerous trials, assaults, and struggles before finally locating the Well. Kartag sought to stop them from approaching the Well and challenged Thor to combat. Kartag's ally, Satrina, prevented the Warriors Three from interfering with the battle. Thor and Kartag fought back and forth briefly until their struggle brought them into the Well itself. Thor was overwhelmed by the myriad of images, of past, current, and future events, which assailed him. Under the direction of his masters, the Fates, Kartag pulled Thor from the waters. The Fates revealed that his quest for the Well had been a test, to see if his race was worthy of saving. They had passed the test, and so the Fates granted Thor and his allies three large sheepskins filled with the waters of the Twilight Well.[1]

Kartag then joined the four warriors in returning to Asgard to join the battle against Mangog. They found Asgard missing; the Rainbrow Bridge coming to an abrupt end. (Odin had relocated Asgard to a distant dimension, so that Mangog could not continue on to the other realms if he proved victorious over the forces of Asgard). Thor used the waters of the Twilight Well to enhance the magics of his own hammer, Mjolnir, and locate and travel to Asgard. Kartag attacked Mangog, but was quickly swatted aside, knocking him a great distance from the battle and apparently incapacitating him as well. Thor sent Volstagg to take the waters of the Twilight Well to Odin's Vizier, while he stayed and continued the struggle against Mangog. The Vizier combined the waters of the Twilight Well with those of Odin's Cosmic Well. This generated large amounts of magical power, which had two effects: The landmass of Asgard began to return to its location within its original dimension. In addition, geysers of water shot up across Asgard. Odin allowed the waters to pour over him, replenishing his might, so that he could again confront Mangog. Odin succeeded in severing the link between Mangog and the energies which initially created it, causing Mangog to shrink out of existence. The drain on Odin's weakened form was too much, and he died. However, as Asgard was in transport across time and space, Odin would not truly be dead until Asgard returned to its original location, and Hela could claim his soul.[2]

With the battle against Mangog concluded, Kartag returned to World's End to continue to defend the Twilight Well. The Fates watched via the Twilight Well as Thor fought off the hordes of Hela and then Pluto, who sought to usurp Odin's soul. Thor nearly fell beneath the axe of Pluto, but the Fates themselves interfered, destroying Pluto's axe and allowing Thor to continue the battle. Thor managed to fight off Pluto, and Odin was successfully restored to life.[3]


Kartag is large and possesses superhuman strength and durability. He is apparently immune to the effects of aging, and possibly of conventional disease. It is also possible that the Twilight Well exists within a division of Limbo, and thus shields him from the effects of time.


He is a reasonably skilled warrior.
