Gravis' mind started racing as it went through a ton of eventualities.
They were connected? How would that even be possible?
The first person that appeared in Gravis' mind was his childhood friend Stella since they had the same name. This would also coincide with the time Arc had mentioned.
However, even if Gravis gave this Stella the maximum amount of time possible, it wouldn't fit. Assuming that Stella was an Ascender, which she wasn't, it would only add 10,000 years to her potential life. Together with the time Gravis had stayed in the highest world, barely 30,000 years could have passed for this Stella.
Yet, Stella was 100,000 years old. That still left 70,000 years unaccounted for. So, when his childhood friend Stella had been created, this Stella had to have been at least 70,000 years old.
