The Well of Sparks (Transformers: Prime Wars Trilogy)
0The Well of All Sparks came into being when Megatronus killed Solus Prime, and her corpse unexpectedly melted its way underground to the core of Primus and Cybertron, becoming the Well of All Sparks. After the climactic battle which splintered the Thirteen Primes, the mortally wounded Onyx Prime chose to travel to the Well, where the presence of Primus would sustain him forever. He would use his Triptych Mask to enable the new race of Cybertronians to have as much diversity as Primus had created the Thirteen with. Micronus Prime chose to accompany his friend to his eternal retreat, and Thirteen chose to accompany them so that he would be reborn as one of these new Cybertronians so that he would be able to help them by experiencing their lives. After Thirteen, Micronus, and Onyx vanished into the Well, the power of the Triptych Mask sent forth a universe-spanning beam which scanned and transmitted back information on the universe's life on which new Cybertronians could be modeled. For the next three days, new Cybertronian lifeforms of all shapes and sizes emerged from the Well. Thereafter, the Well would occasionally send forth new beings to replace the dead or simply to introduce new life to Cybertron until the planet became a lush, rich world.
