Massive mercenaries with formidable strength
The Gigas were originally from an island far to the north of Quon. Every few decades, the Gigas send a large ship to Qufim to attack the Hume settlements. Their goal is to retrieve supplies and slaves to take back to their homeland. Before the Great War, the Shadow Lord recognized the potential that lay in the giants, and hired a large number of them to fight as mercenaries. After helping to construct Castle Zvahl, the Gigas led the beastman frontline in laying siege to many of the allied forces' fortresses. However, when the beastmen lost the war, the remaining Gigas were left trapped, unable to return to their homeland in the north. With nowhere to go, they set off for Qufim and Delkfutt's Tower, where they remain today--out of reach of the allied armies.
Gigas Many Gigas live in chilly climates, but still they only wear a little leather around their hips and on their feet, accompanied by their necklaces and arm bracers. Gigas and Giants in our regions have a dark green body color which is the result of living so long in our relatively warm climate.
Jotunn Jotunn are a smaller tribe that hail from even farther north than Gigas. To protect against the cold, they wear fur around their waist and as socks. They come from frigid areas where it snows all year round, which has given their body a pale blue color.
Uranos Brothers These are brothers of the Uranos family. They have grey bodies and are said to be royalty who are born with the blood of the divine. The tattoos that cover their bodies are a map of their royal lineage.
Uranos Bracers These bracers are crafted by the few Gigas that are metallurgists. They are forged with immense power that is beyond the capability of any human blacksmith. It is said that power dwells within the bracers themselves and is transferred to the wearer. This is especially true of the bracers worn by those of the Uranos clan, whose arm bands are famous masterpieces and are envied by many.
