In the original novel, Lia's mother dies of other causes.
It wasn't properly explained why she died; perhaps she died from a failed dungeon raid or some other reason, but she definitely didn't die from a curse.
Rio has been confused about this situation ever since he heard about it from Lia.
Now he finally knows why this happened.
'Something changed the course of history; something caused that higher entity to notice Alverto and then in turn Alverto used curses to spread a wide net for the one favoured by heavens…'
The curse was extremely hidden and was cast with the power of an entity that even peak SS rankers can't contend with; thus, no one could even notice it or deal with it.
Usually, the curse would stay inactive as long as the curse bearer doesn't come in contact with the one favored by heavens.
But a curse is still a curse after all; moreover, this one has the power of an extremely powerful entity.
