Sometimes, Legacies are called the horsemen of the apocalypse--harbingers of the End of Time. This is both true and preposterous. This is true in that when all Legacies have come to pass, that the end of the known world will be nigh. Likewise, there can be no end to time; it will ever flow onward--there can be only change.
NOTE: Legacies are always spoken of with the definine article: the Titanomachy, the Exodus, the Deluge, etc. In a way, these archdaemons only have epithets, and not true names.
Warlocks with Legacy patrons may use the homebrew Horologius patron until such time as an appropriate "official" option is released.
Legacies of the Past
These Legacies' effects on the Mortal Plane were experienced and understood in history, but continue to have lasing effects.
The Titanomachy
The conflict between the HMDJVNW and the giants of Raviq lasted for centuries. During its course, the giant races were decimated, and their remnants ultimately exiled from Orbimond; their legacy was carried on in the goliath races. The land of Prosperity was even physically transformed into the land of Desolation, and the Taint was unleashed upon the mortal races of he world. Had the HMDJVNW not arrived in the mortal world, however, the war of the giants would still have occurred--instead against the might of the dragons!The Titanomachy is the archdaemon of the giants (though giants do not dwell in Eternity).
