The Great Warriors are incredibly powerful warriors who accompanied King Zahard in climbing and conquering the Tower. They were Zahard's companions. They are all technically Irregulars, but they are not considered so in current Tower society.
After Zahard stopped climbing the Tower, the Great Warriors ultimately became The Great Family Heads, the heads of the families known as the 10 Great Families in modern Tower society.
The 10 Great Warriors are the founders and heads of the 10 Great Families, thus possessing great political power as well as great combat prowess. They are among the strongest Rankers in the Tower, and some of them are even ranked as high as within the Top 10 High Rankers.
He also commented on their invincibility, stating that the Family Heads have little reason to fear FUG unlike the members of their respective Families. However, even they start to get a bit irritated when a FUG Slayer emerges, due to FUG's terrorism against the 10 Families. Grace Mirchea Luslec, the founder and strongest member of FUG, is stated to be capable of making the Family Heads act directly if he personally moves.
According to Garam Zahard, there were originally 12 companions that accompanied Zahard, but two of them, Grace Arlen and V, rebelled once Zahard decided to stop climbing and become King. However, the other Great Warriors remained on Zahard's side. Following the aftermath of the civil war, all public records of the conflict and the two's existence were suppressed.
