Toadkiller Dog appeared to be a big white dog with red eyes and taste for beer. It was often seen with his partner, a muscular man known as Tracker. In reality, he was a powerful demon loyal to the Dominator, and in search of a method to resurrect his master from his prison, the Barrowland. His power and durability were immense, and he was even capable fighting a number of the new Taken.
The White Rose Edit
The Black Company met it during their stay in the Plain of Fear. The dog and Tracker were sent to deliver a message for Croaker. The two spent some time with the Company and joined their military operation in the city of Rust. During the retreat from the city Toadkiller Dog was left behind. Tracker became irrationally upset after losing his friend. Fortunately for him the dog managed to return to the Plain of Fear by itself and was found by Croaker.
Croaker also took the dog and its owner on their next mission, which was in the Barrowland. They were arrested there and had to break out of prison. During their escape through the Great Forest, Toadkiller Dog intercepted the chasing soldiers and killed over a hundred of them in the fight. During the retreat the dog clashed with a number of the new Taken, and successfully fought them off, as well as injuring Whisper.
Later Toadkiller and Tracker return to the Plain of Fear once again. There the dog attacked the Lady, who was defenseless, but Father Tree intervened. Toadkiller Dog's true nature was revealed: it was a demon in service of the Dominator. Afterwards the demon returned to his master in the Barrowland, in order to guard him against enemies. In the Battle of the Barrowland, Toadkiller Dog fought for his master and mustered a large force of tribesmen from the Great Forest. During the battle he lost one of his legs and was forced to retreat.
The Silver Spike Edit
Toadkiller Dog returned to the battlefield and spent many nights digging for something, which turned out to be a severed head. Witnessing this, the spike thieves delayed their attempt to steal the silver spike until it had left. Toadkiller Dog forced the forest shamans of nearby tribes to create an artificial body for the head. The head on the "amalgalm" was actually the Limper, who was intent on seeking revenge against Lady and Croaker for his decapitation in the battle. He and the dog lead a small army, which at first consisted of 50 tribesmen, and they sacked what remained of the town in the Barrowland. As they sacked all the cities in their way southward, Imperial soldiers also joined, fearing the Taken's retribution if they refused. They besieged the Tower at Charm with 5,000 soldiers, but were unable to capture it. They pillaged Opal, crossed the Sea of Torments to attack Beryl, and rampaged south. Along they way, somewhere outside the boundary of the empire, they captured a dormant fire-eater.
They were defeated by Darling's army of Plain of Fear monsters at the Temple of Travellers' Repose. Still having a use for the Limper, the dog travelled East to the country of Sweeps. There he created an alliance with family of wizards called the Nacred after he helped massacre their rivals the Shaded. Honouring the deal after witnessing the creatures power, the wizards finished a gorgeous new clay body for the Limper's horrid head. However, once being fully reconstructed the Limper betrayed them and the demon by trapping them in the Temple's subterranean chamber.
After forcing the survivors to dig a way out and feeding on those to weak to work, the monster alone escaped the ruins. The demon returned north to chase the Limper fueled by vengeance. He was encouraged all along the way by the heirs of the Lady's empire, who guided his return and struck an alliance with him at the Tower at Charm. In the city of Oar, the ancient demon was killed while trying to take down the mad sorcerer.
