- “The Seed is soul and life. And it's amazing. It's tied to the heart of the Earth.”
- ―Willow Rosenberg[src]
- “Think “cork”. As long as it’s in its place […], things stay more or less where they should.”
According to Spike, the Seed of Wonder predated humans and even the First Evil, the Earth itself created from the Seed. In the beginning, the world was inhabited by demons — Old Ones —, who were probably spilled over from “far more horrific” dimensions. The Seed had brought them to Earth, and the Seed that kept them there, the only thing strong enough to prevent the warring creatures and magical energies to bleed back into the unknown older dimension.
The Twilight Crisis
- “The Earth demons won’t want the new-universe demons to get [the Seed]. ‘Cause if they do... [uncorks a wine bottle] Well, imagine this bottle is upside down.”
With the threat of the masked “Twilight” — Angel —, Buffy and Willow went to Sephrilian to seek help against him. The Tichajt made Buffy, Willow, and the minder Robin walk among visions of betrayal, which included a scene of the cracked Seed on a podium in a circular stone room, while another Buffy cried beaten on the floor. It was revealed by the minder it was a vision from the future. The same room appeared in one of Buffy’s dreams, foreshadowing to the Slayer the upcoming decisive event that would happen at the place.
The Master was enslaved by the Seed approximately 800 years earlier to keep custody over it. When Buffy became imbued with the power of Twilight, the Seed resurrected the Master to watch over it. As the world’s soul and the source of all its magic, Twilight needed to capture it so that it would become the new universe’s soul, destroying the old one.
The Seed was safe, though buried underground in Sunnydale with its protector at its side, until the universe selected Angel and Buffy to conceive a new universe with each other. The demons of the new universe poured in through countless portals to seize the Seed for Twilight, while the demons on Earth first tried to repel them.
As Aluwyn elaborated to Willow, removing the Seed to the Twilight dimension would cause the world to be swallowed up, allowing Twilight to fully come into its own. However, breaking the Seed would sever all magical ties with other worlds and Earth’s connection to other dimensions; the analogy being the difference between removing a cork from a bottle and breaking it so that it remains stuck at the top of the bottle.
- “Have you ever broken a cork inside the bottle? You'll never get this one out, and the wine will be forever trapped. Destroy the Seed, the gate and the path are gone. Hell has no avenue to your world. And you have a world without magic.”
While Buffy and Angel (possessed by Twilight) battled in the ruins where the Seed was being held, Giles brought Buffy the Scythe. The weapon began to glow red as its power grew in the presence of the Seed. After Angel killed Giles, Buffy, in a fit of devastation, used the Scythe to destroy the Seed, and ended the battle against demons and Slayers.
The destruction of the Seed immediately depowered witches throughout the world, while active spells were severely weakened or simply broken. Creatures with inherent powers, such as vampires and Slayers, retained them. However, no more Slayers could be called, and no more demons could enter the Earth dimension, resulting in all new vampire sirings only resulting in zompires. The effects of Mohra demon’s blood was also altered, so that instead of simply being regenerated to health, many recipients would develop painful cancerous growths all over their body.
Apparently, the Seed’s destruction also affected the natural world and humanity as well. According to Willow, there hadn’t been a decent song, movie, or book released since the Seed was destroyed, suicide rates were spiking all over the world, and people were losing hope, with things expected to get even worse from there.
RestorationAfter months with no magic, Buffy, Willow, and Xander made their way to the Deeper Well when Dawn began to fade out of existence due to the loss of magic. As they went deeper into the Well, a new Seed was spawned directly from Willow’s body, rendering her powerless in the process. Willow proceeded to find a spot in the Deeper Well to plant the Seed; while it would save the world and eventually restore Earth’s magic, it would not fully mature for a thousand years.
However, Severin, who had absorbed many demon’s powers, including those in the Deeper Well, with the intent on using that power to go back in time and revert the Twilight apocalypse, was persuaded to instead redirect all of his powers into the Seed. The new Seed was aged to completion and restored Earth’s magic, but caused a magical blast that completely vaporized Severin and Illyria in the process.
With the sudden return of magic, the Slayer Handbook’s pages turned completely blank. The rules of magic were being gradually rewritten, such as the Slayer prophecy and new vampires with new abilities. The formation of a new Seed also allowed Dawn to be made into existence again, albeit in a reset of feelings and memories. Illyria, the Old One who sacrificed herself for the Seed, also returned to life with the new magic — within a resurrected Fred Burkle.
