Grumpa Archibald Achielles was born to the parents of Garomor and Sallii Achielles in the Northern Human Kingdom of Gilneas. From an early age his parents could see like his older brother, Grumpa would be able to use the power of the Arcane. When Grumpa was six his younger sister Hilga was born and she was different to both Grumpa and Robert (Grumpa's order brother) in the fact that she was a Druid. During his childhood Grumpa held a closer relationship with Hilga rather than Robert. Something that would be shown later on in his life.
