Given that claymores come from different generations and the definition of a generation is vague, it's hard to tell how old warriors are. Even awakened beings who are former warriors.
Clare looked to be about 8-10 when she met Teresa. Teresa was already an adult. She didn't appear to be still be still maturing physically, the way we see Priscilla and Clare throughout the series.
Let's assume Clare is 15 at the beginning of the series. By the end, she’s 22.
Let's assume each generation is 10 years, for easier math:
Teresa would've been in her 20s, let's extrapolate from that that Ilena was in her 30s by the end of the series.
Rafaela was an adult when Teresa was still a trainee. Between Luciela and Teresa as number 1s, there were at least two other number 1s: Hysteria and Rosemary. Rosemary was rising in rank at the same time as Teresa. Rafaela then wouldve been in her 30s when she met Teresa as a trainee.
Riful is much older. There have been many number 1s that we never learned about besides names and perhaps more who simply disappeared in history. Number 1s awakening is rare, given that by the start of the series, there are three on the continent and Priscilla who is beyond the ability of an abyssal one.
Riful, as a first generation warrior, is easily over 60 years old. Isley over 70.
“Black power is the dungeon-side view of Monticello—which is to say, the view taken in struggle. And black power births a kind of understanding that illuminates all the galaxies in their truest colors. Even the Dreamers—lost in their great reverie—feel it, for it is Billie they reach for in sadness, and Mobb Deep is what they holler in boldness, and Isley they hum in love, and Dre they yell in revelry, and Aretha is the last sound they hear before dying. We have made something down here. We have taken the one-drop rules of Dreamers and flipped them. They made us into a race. We made ourselves into a people.”
My fav version of poison ivys power origin story is a lá Thorns (medically tortured as a kid) and when she learns about a literal child following batman around she FREAKS OUT.
Ivy gets batman alone then serves him a total curveball: she wants to vaccinate Robin from most of her toxins. Bruce thinks it’s a trap until word on the street is that Scarecrow and joker had multiple poisons stolen. He confronts ivy and she admits to stealing them but it’s for the proposed vaccine for Robin.
The rules are that he’s not allowed any samples of the vaccine, and Robin stays with her for three hours for the vaccine to fully absorb into his system. Batman can stay with him, but only in the same room as she might need to use lab equipment.
So every Robin gets the very odd experience of having their biannual vaccine from Dr. Poison Ivy, where they are all on their best behavior and get biodegradable stickers while Bruce just very patiently sits next to them like >:| with one of those temperature guns aimed at their heads
