Urgan Nagru, also known as The Urgan Nagru and The Foxwolf, was a male fox ruler of the Land of Ice and Snow. He found the carcass of a dead wolf and took its pelt for himself. Fixing iron hooks onto the claws of the pelt, he found that he could strap his own paws into the wolf's paw area and wield them as deadly weapons. He also used the skull of the wolf as a helmet. With this intimidating attire, he assumed the wolf's name, Urgan, and then spelled it backwards for his new surname, showing his enemies that he could come from the front and behind.
Urgan was the mate of Silvamord. Like many vermin leaders, he did not appear to actually like his mate. The pair distrusted each other and constantly bickered to the point of violence.
Eventually, Urgan and Silvamord grew tired of their frigid land and sailed to warmer southern regions, specifically Southsward, with three ships and an army of rats numbering approximately 500 strong. Nagru and his mate deceived the monarch Gael Squirrelking into thinking they were peaceful creatures and gained entrance to Castle Floret. A few days after their arrival, Nagru held Gael's son, Truffen, hostage and threatened to kill him if Gael didn't abdicate the throne to Urgan. Gael was forced to resign, and the army took over the countryside.
After that, life was pretty easy for Urgan. As ruler of Southsward, he believed that he had no enemies and was completely safe. However, unbeknownst to him, a loyal otter named Rab Streambattle, the leader of Gael's Otter Guard, planned to free the king and his family from the castle. Rab succeeded in rescuing Gael's wife Squirrelqueen Serena and Truffen, but couldn't get to Gael. Urgan, outraged, chased after the otter, but was held back when the badger nursemaid Muta ran to Rab's aid and stalled them long enough to make their own escape. Urgan ordered that his army find the escaped prisoners and any who aided them, and return them to him.
He sent out his dreaded trackers, the Dirgecallers, to locate the escapees, but they were killed by Mariel Gullwhacker, Dandin, and Meldrum Fallowthorn the Magnificient. Urgan consoled his loss by capturing the trio, but was surprised when they escaped the dungeon, joined with Gael and Glokkpod, and formed a blockade in the highest tower of the castle. He was furious that his mighty army couldn't even hold on to a small group of woodlanders, who by now had escaped the castle.
Soon enough, Gael reappeared to storm the castle with a mighty group of Southswarders who were willing to fight for their freedom. None of them counted on Urgan Nagru's cunning as a general, and soon they were the ones in need of assistance. But then, to the utter dismay of Nagru, another army led by Joseph the Bellmaker appeared and started to force the Foxwolf's army back. Left with only his personal guard, Nagru tried to make his way back to his ships, but encountered Finnbarr Galedeep. Nagru and the otter then engaged in a vicious wrestle. Although the Foxwolf put up a fierce fight, he was eventually lifted up by Finnbarr, who rammed Nagru's head into a nearby tree. The curved fangs on Urgan's wolf skull helmet were driven into his own skull, killing the Foxwolf and permanently ending his tyrannical reign over Southsward.
