The Arezages Gustoi nobles form the celtiberian chieftain's bodyguards and their loyalty has no bounds.
When a Uramos (war leader) of the Areuakoi sits atop his steed and surveys the men assembled before him or examines the enemy yonder, he needs to be assured that the men who ride by his side will do so to the end, even if they must escort him into the otherworld. The Uramos need not worry, for not only is it illegal to survive one's leaders in battle, but it is a thought abhorrent to all but the most craven Keltiberoi. Selected from among the ranks of the regular Arezages Gustoi, these men are an elite corps. Their bravery, loyalty and ferocity cannot be equalled. These Arezages Gustoi live, breathe and drink the heroic mantra; that it is better to enjoy a heroic and glorious death at a young age, than to suffer to live to be an old and forgotten man. The bards sing songs of how many a Arezages Gustoi, upon seeing their Uramos hard pressed and near overwhelmed, have used their bodies as shields, thrown themselves in front of charging horses, or stripped nude and charged to certain death upon hearing of the death of their leader. The generals of foreign lands might wear more armour, or surround themselves with a larger retinue, or even ride to the battlefield in hulking chariots, but few can claim to have a bodyguard as fanatically devoted and loyal as the Arezages Gustoi.
Historically, the law that Keltiberoi were forbidden to survive their leaders in battle, was a feature which was by no means unique to the Keltiberoi: the Gallic soldurioi and ambaktoi are recorded as having done the same, as are the bodyguards of German war leaders. The story of the Numantian Retogenes who broke through the Romani siege defences with five comrades, in order to try and raise help from among the Areuakoi, may belong to this tradition of dedicated bodyguards. Likewise the story of the Areuakoi leader Karos may be another example of this type of dedicated service. When Karos was killed pursuing a Romani force, 6,000 of his followers, according to Appian, fell with him as he performed acts of valour. The leaders who led these bodyguards likely did so at the request of their retainers. Keltiberoi generals attained their positions through election rather than birthright. Karos, for example, was elected to lead the armies of Numantia and Segeda; two generals named Ambón and Leukón were also elected to lead the forces of Numantia, and in 153 BC the Areuakoi voted for war. This combination of ferociously loyal bodyguards and a command system based on democracy would prove ideally suited to Romanisation, with many Keltiberoi later enjoying prominent careers in the Romani army and government.
