My idea of age spans for the Bara Magna inhabitants (main cast)
Ackar ; Late 40's - Early 50's
Kiina ; 16 - 17 (this woman doesn't act like an adult istg)
Gresh ; 17 (same with this mf)
Berix ; 8 - 10 (I will forever believe he's malnourished/mutilated halfie Agori Glatorian kid on the streets it just makes the most sense to me)
Tarix ; 27 - 30
Vastus ; 28 - 29
Strakk. ; 30 - 32
Tuma ; 29 - 30
Metus ; 56 - 57 (man has that experience with being a snake (pun intended) so yeah, older than Ackar but not old enough to be for village elders)
Raanu ; 79's - 80's (I imagine the village elders are usually between these ages, even with mechanical upgrades from the Great Beings that ended up to be even genetic with enough trial and error to be fully successful with the lack of basic resources it would be heck of survival skills to live so long to those ages and ofc those skills would be taught but luck also takes in turn as well)
Cervantus ; 21 - 28 (I imagined one of the greatest Glatorian's, Cervantus would be one of those young prides who rises ranks pretty quickly at a young age (like Ackar as well) before his death)
Malum ; 26 - 29
