Olaf Johnson (Baldr) says that he is 92 years old, so born around 1919. We learn that the Napier/Hastings earthquake of 1931 was the result of earlier incarnations of the gods failing to find Frigg before Odin died, and it killed them all. Gods come into their power at the age of 21 (so around 1940 for Olaf).
How do these times fit together? Olaf was alive (and so presumably a reincarnated god) in 1931, but not among those killed by the earthquake.
Did he survive somehow? (Because he hadn't come into his power yet, maybe?) Was there another Baldr in '31, and he transferred into Olaf later somehow? Was Baldr not one of the reincarnated gods that died in '31?
