The Reasoning behind The Sundering? (*6.0 Endwalker Spoilers*)

[Erendis]

This is interesting to me though because, based on Elidibus’ memories at least, Lahabrea was sane enough to still go out and care about Elidibus’ well-being when he too was working himself too hard. So he couldn’t have been that far gone unless they forgot about that or retconned it lol

It does not seem likely that old Lahabrea, who did not care much about his son, would somehow care about Elidibus. It is much more likely that Erichtionios, who met Elidibus in Pandaemonium and thus came to care about him, is our Lahabrea.
