In the Arcane lore doc, there’s a section that reads this:
“Soon after creating all of the normal Curses, Prometheus knew that Cursebeard would soon kill him. In his panic, he created the Grand Fire Curses, in hopes that a human would absorb them and defeat Cursebeard someday. Cursebeard was unaware of this, and he promptly absorbed the Blaze, Tide, Ice, and Energy Curses. Prometheus imbued the Grand Fire Curses with his own Grand Fire Magic.”
The last sentence says something of “Grand Fire Magic”, but what exactly IS Grand Fire Magic? Why does it do, and why did Vetex add it in?
grand fire is basically all of the different aspects of fire embodied and amplified, darkflame for spreading, scorch of explosiveness, aethreal for brightness, inferno for heat, and promethean flame for all of them and its basically just the magic form of the respective curses.
grand fire is used by prometheus because that’s his element, like how zeus has lightning and poseidon has tide/water, and hades has earth.
its not headcanon, its literally the different aspects of the grandfires,
before the lost/ancient list got wiped by vetex it said something along the lines of darkflame, focused on spreading
inferno, powerful fire
aethreal flame, focused on brightness/blinding
scorch, focused on explosiveness
promethean, the rarest and most powerful magic of all time etc etc.
Nah they exist, seeing as the grand fire curses are in the lore and some of the grand fire magics existed in AA and are planned for AO. Tech has explained which aspect each grand fire magic embodies
prometheus’ grand fire is likely as powerful or more powerful than the curses he created, it would be weird if he used the magic version if he could create the curse version and just use that.
