Gulla and a large band of goblins were dispatched by the moredhel to aid in an assault on Northwarden. When brought word that the party has arrived and has been heard wondering how to pass through the goblin horde, Gulla approaches them and, in broken Kingdom tongue, requests a "new contract" with the Kingdom, whereby his troops would fight for Northwarden in exchange for 2000 sovereigns. Once the party pays, Gulla allows them to pass through.
As the party moves north, they defuse further goblin encounters by mentioning Gulla's new contract. Though bewildered, the rest of the goblins accept Gulla's new orders to fight for the Kingdom.
