Well of the Great Sparks

The Well of the Great Sparks, located under the surface of either Protihex or Altihex, is the place where Transformers go after they die, the Transformer "afterlife". Also known variously as the Matrix, it is the nigh-indefinable extradimensional realm, or even force.

At the heart of an endless, cyclical process of birth, death and resurrection, the Well it is both the source and destination of all Transformer sparks. When a Transformer is brought online, it is commonly through use of a sacred implement which serves as a means of access to the Well of the Great Sparks. Through this implement, a Spark departs the Well, and enters the new Transformer's body, granting it life. The Transformer then lives out their life, and upon the moment of their death, their spark will return to the Well, taking with it all the emotions, experiences and knowledge that the Transformers has gained throughout their time online. This knowledge is suffused into the Well, gathering with all the other knowledge of all the other sparks from throughout time, forming a collection of information known as the "Wisdom of the Ages".

There is little individuality within the Well, however; the individual Transformers' experiences become one with all the others in the Well, and they effectively cease to exist as a singular entity. Some Transformers do retain their individuality, however—typically, those who have had close contact with sacred implements, such as the Autobots who have carried the Matrix of Leadership, remain self-aware within the Well of the Great Sparks, and can serve as guides for any visitors into its realm.
