where was it said that calvus ruled for 24 years? We know that calvus took the throne at 11 and that revon was 3.
(Side note: But if this holds true I would have correctly predicted both Calvus’ age and the number of sons Wotan has prior to the reveal)
it was never said anywhere, whoever wrote that probably just made up a random number 
we just need 2 know when cassia bay happened then we can deduce when calvus took the throne
nero ruled for 70 years b4 dying, calvus took the throne at a ‘very young age’ which isnt specified anywhere in game i believe
octavious*
while i agree that is is a random number, given that octavious ruled for seventy years and the arrest of nero was sometime after Y1750 (fall of winterveil), then he must of ruled for somewhere in the ballpark of 15-30 years rough estimate.
Use what we know, he took the throne at 11, and he must be older than 21, given the fact that he has children that are young, but not incapable infants.
I’d venture to say his oldest daughter is around 7 as thats the conclusion i came to during early access. and given Calvus’ appearance I came to the conclusion that he is around 35 years old, (I actually think I might be dead on with this prediction)
The also must mean in this case that Octavious became a father at 74 and once again at 81 which is bonkers to me, but given the fact that he was a pretty capable mage and that skews the aging by quite a bit I guess it isn’t all that crazy
yeah octavious mb
