Fëanor escreveu:A verdade é que Karsus se arrependeu no momento que conjurou a magia, porque ele queria se tornar um deus, mas não ás custas de outro. Apesar de ele ter sido o criador da magia, ele não sabia que Mistra iria "morrer" no processo.
Na verdade, saber que ia morrer ele sabia, mas não sabia das consequências dos seus atos.
E depois disso, as consequências nunca mais foram as mesmas...
É Karsus: You dun goof'd.
Alias, achei! Lord of Darkness, da 3.0 explica melhor:
WHAT REALLY HAPPENED
Karsus the arcanist decided to merge with Mystryl, the Netherese deity of magic. The result was catastrophic. When his essence combined with Mystryl’s, the deity lost the ability to maintain the Weave. The goddess sacrificed herself to save the Weave before the damage became irreparable, but in so doing she temporarily obstructed the Weave, ending its connection with Faerûn. Karsus was killed by the experience, just as he had predicted, but he did not gain Mystryl’s divine power for a period long enough to wield it successfully. The wholesale cessation of magical energy sent arcane shockwaves throughout Faerûn, since all spells and wondrous items ceased to function abruptly. The survivors of this catastrophe and their descendants were responsible for the rise of the now-ruined empires of Anauria, Hlondath, and Assam, but Netheril itself was gone. Eventually, Mystryl was able to reincarnate herself and restore the Weave to its proper state, but it was too late for the people of Netheril. The folly of Karsus had done what the phaerimms had been unable to do: The Netherese Empire was no more.
The body of Karsus, made gigantic by the influx of divine energy, fell to earth as he died. It shattered, leaving a silent reminder of his folly to future wizards—a single red stone butte at the base of a high cliff in what is now the Dire Wood.
