In just a few minutes, a clear and clean path was created after the total obliteration caused by Forne and the rest. The ground was turned into lava, the air filled with exploding red particles and the purple orbs which acted as some sort of black holes, sucking everything close to them. The usually mindless Cthulhu didn't recklessly charge at them after witnessing this bloody massacre, their forces slowly backed away, shocking obvious signs of dread.
The tall and golden-eyes ones kept firing arrows which decayed before they even crossed half the distance. So, just like that, Forne's team arrived before the Sky Door within three minutes, more or less.
The giants dragging the massive chains weren't able to defend themselves so they were cruelly killed by the rampaging Void Behemoth, which ripped their heads, leaving nothing but lifeless and headless corpses.
