Spoiler alert : this contains information from quests for glory
Gus and gagan are male and probably antagonists in gavaldon.
They work at their father papa pipps pub , where they worked as waiters.
They have a younger sister named Nicola of woods beyond.
Papa pipp knew that as soon as he died his sons Gus and Gagan would sell the place and so he declared that Nicola would inherit the pub and Gus and Gagan could be kept at bay serving foods.
Nicola beat Gus and Gagan at every sport they played.
In quests for glory Gus and Gagan submitted Nicola into the school for good and evil in quests for glory but however in the ever never handbook her application states that her friends Hunter wrote the page for her.
