If Sverre had expected to sit at ease in the enjoyment of his power, he must by this time have been undeceived. He had indeed sown the wind, and he reaped the whirlwind. No sooner were the Kuvlungs out of the way than a new band, called the Varbelgs (Wolf Skins), was organized by the chieftain Simon Kaaresson, who picked up a pretender in the person of a child, named Vikar. This boy, who was but a few years old, was born in Denmark, and was alleged to be a son of King Magnus Erlingsson. But the deception was a little too barefaced to gain credence, and the Varbelgs came to an inglorious end at Bristein, near Tunsberg (1190), where both the little Vikar and Simon Kaaresson were slain. Rebellion had by this time grown so popular that any plausible impostor, who chose to take the risks, might expect to gain a considerable number of adherents. The many who were unable or indisposed to put up with the new order of things, preferred to stake all on a desperate chance rather than submit meekly to the terms of Sverre's amnesty. It was, therefore, of small consequence who headed the rebellion; the rebellious spirit which was abroad was sure to find expression, and was never in want of a leader. The successors of the Varbelgs were called Oyeskeggs (the Islanders), because their band was recruited largely from the Orkneys, where Earl Harold favored them. Their chieftains were Hallkel Jonsson, a brother-in-law of King Magnus, Sigurd Jarlsson, an illegitimate son of Erling Skakke, and Olaf, a brother-in-law of Earl Harold, of the Orkneys. All these had nominally submitted to Sverre and had received many favors at his hands. Nay, even after they had hatched their conspiracy, Olaf continued to act as the king's friend and sit at his table. Sverre was, however, not deceived by his duplicity. One day when they were talking together the king said: "Thou, Olaf, oughtest to have been faithful to me." "Why do you say that, my lord?" asked Olaf. The king, instead of answering directly, made a thrust with his knife in the air and said: "The followers of our foes are now swarming about us." At this the traitor took alarm and quickly left the hall. Outside he met his foster-son Sigurd, who was said to be a son of King Magnus, and was later pushed into the rôle of a pretender by the Oyeskeggs.
