Days before the letters were sent out...
A human researcher and his bio-mechanical friend finish working on a machine. A machine called the "Energy Synthesizer," made to synthesize energy. The researcher starts writing a letter:
The chaotic, scheming, dangerous being who seems unkillable. He should not be trusted. He always moves towards his goal. Symphony was once dead, before Makuta brought him back.
Symphony gains power through the dead. He can absorb their Unknown Energies. These Unknown Energies are what make him more powerful. They appear in three different colors, based on their alignment. Yellow-white is the alignment of Light, Red is the Alignment of Neutral, Purple-black is the alignment of Dark. All these Unknown Energies appear like glowing strands of string or hair. These energies seem to lie dormant in every being, but none of them seem to be able to access them.
Symphony takes these dormant energies from the dead bodies and add them to his own. He releases the energies from their old bodies. He treats this as their burial service, because the bodies disintegrate from the loss of these energies.
He relishes in the chaos of others, though he believes chaos is not needless destruction but something more terrifying. Symphony has only one goal, true chaos. He will do anything to accomplish his dark goal. He seems to have only two things he will protect, his sister and his sister’s good friend. Symphony has had multiple variations over his life, each one getting stronger. On researcher made the parallel that Symphony is like a sponge. Well, a sponge that is limited by how much water is in it. The researcher remarked that Symphony gained more room for more power as he gains power. This means he’s like a sponge that hold more water as more water is given. He was unable to determine Symphony’s limit, but we know there is an absolute limit. That limit is all the Unknown Energy in the Universe.
We call that hypothetical realm the “Symphaverse,” for it’s terrifying prospect. Imagine a realm that is the chaotic Symphony and nothing else. Beware of Symphony and if you are able to kill him, do it. Kill the fiend.
The researcher puts down his pen. He looks at the mechanical being close to him, “Send this to all beings with the power level of twelve and above! We don’t have enough time!” The biomechanical being nods at the human, he types the message into a machine.
Crack! A shimmering, azure portal opens. The bio-mechanical being pushes a machine through it.
Crack! Crunch! A loud, shattering crack is heard at their door. The human researcher looks at his bionicle friend, “I think its our time…” tears fall from his eyes. The metal room they made their fortress is paper in Symphony’s wake. The building slowly crumbles blocking any escape and cutting off the power. The matoran hold his dear friend. The clangor of crumbling metal engulfs any scream they could produce.
Suddenly the building splits in two and the two beings meet an array of giant ropes of light dangling from the sky. The appeared in three colors yellow-white, red, and the most numerous, purple-black. Symphony is here.
A okotan mask falls to the ground and hovers. It’s Symphony’s mask. The mask hovers closer to the two beings. Its mouth opens, shouting into the broken wasteland, “Where! Is the Energy Synthesizer!”
The human researcher laughs, “It’s gone Symphony and everyone knows you’re coming! So! Kill me now! You have-”
A blade of metal shoots from the ground and takes the researcher’s head. The matoran cries aloud before suffering the same end. Symphony is mad. The sky fills with darkness only lit by his unknown energy. His plan is now in action sooner than he planned.
Azure portals open up above their targets, the letters drop down. Geet grabs the letter that drops in front of him and reads it. His eyes fill with anger and he crumples the letter. A golden portal would open before all the targets, after reading the letter.
Geet spits on the ground,
"I'm coming for you Symphony!"
Geet heads into the golden portal and appears on a plateau. He carries his heavy chain and rests on the edge. The edge crumbles and breaks under the chain weight. A red dragon, shimmering in the sunlight, lands on the plateau. His green eyes rest on Geet,
"Your the first to come. I'm am Antama the Eld. It is good to meet you, brave warrior."
"I'm guessing you're training us."
"Ever since I became bound to this realm, that has been my purpose. To those who find it worthy there are seven powerful artifacts on this Island, each one has a weirdly specific power and name."
