United Quagoa Clans

United Quagoa Clans was an alliance of Quagoa that were brought forth together by Pe Riyuro.

Background
The unity of the Quagoa Clans was envisioned by Pe Riyuro who was considered to be a revolutionary genius amongst the Quagoa. After discovering an abandoned dwarven city, he gathered the clans there and formed monster-fighting units, using dwarven prisoners to develop agriculture and animal husbandry.

Usually, when a new clan leader was born, he would exterminate the bloodline of the previous clan leader. This was the commonly-accepted means by which power was exchanged within the Quagoa people. However, Pe Riyuro did not do that. Instead, he chose to let the leaders of the various clans rule themselves. But Pe Riyuro ordered all the ores to be brought to him so that he may control the distribution. Those who obeyed Pe Riyuro and performed well would be given rare ores, regardless of their status.

The Craftsman of Dwarf Arc
The United Quagoa Clans planned to massacre all the dwarves in the Azerlisia Mountains. One group staged a massive assault on the Fortress at the Great Rift. Another was stationed in Feo Raizo, to kill any dwarf who tries to find refuge. The ones in Feo Raizo ran into Ainz Ooal Gown and his group and were captured and sent to Nazarick. The ones who attacked the fortress found success but were stalled by a gate. The Quagoa were later attacked by two Death Knights who came out of the gate. They were able to defeat the two undead by destroying the bridge, sending them to the bottom of the Great Rift.

Pe Riyuro later assembled all 80,000 Quagoa in Feo Berkana. These Quagoa came into contact with Shalltear Bloodfallen and Aura Bella Fiora, who ordered them to immediately submit to the Sorcerer Kingdom or be reduced to 10,000. Pe Riyuro asked for proof of their strength. The two Floor Guardians took this as a refusal and started the "Quagoa Genocide". Horrified at the sight of all of their warriors being killed with virtually no effort, Pe Riyuro ordered his remaining men to select 2,000 children and slaughter the rest. This led to the United Quagoa Clans being reduced to 4,000 men, 4,000 women, and 2,000 children. The survivors were later taken to Nazarick.

Strength
The Quagoa of the Azellisian Mountain Range were divided into eight clans, all of whom were united under the Clan Lord. They numbered 80,000 in total.
