The Sixth Incarnation is the first Multiverse. When a witch from this Incarnation went rampage, she burned the entire Incarnation and when the Multiverse was reborn, it was filled with fire and no population at all. That witch was named Fivvy and she was afterwards killed by Victoria when she was transferred there the moment she destroyed the Hell of the 14th Incarnation. Victoria after set amount of years found a way and escaped the Sixth Incarnation and was transported to the 14th Incarnation without knowing how exactly she did it. Victoria even stated that the Sixth Incarnation was like an immortal fire that would never be taken down. She doesn't even know how she survived all those years, she said. Assan absorbed all of this Incarnation's magic after its first end and became its Darkness manifestation.
