Okay, so I've literally about 3 leaders to choose from for this civ, which one should I pick do you think?
Konchek-Argurably the coolest, unified alot of tribes and launched devastating invasions on Rus territory. He also allegedly invented Greek fire or something. Despite being one of the most influential leaders, he has no wikipedia page, and I can't find much about his actual life.
Boniak-Prominent Cuman chieftan, nicknamed the "Mangy". Defeated a bunch of peeps like Hungary and the Rus. Apparently did some symbolic stuff? Viewed as one of the greatest leaders.
Koten-Not so lucky with his wars, but fought against the Mongols, and led his people into the Balkans where they settled and founded several dynasties, and for that he is considered quite influential.
