We are a transfinite entity originating from within the horizon of a closed singularity. Upon the collapse and evaporation of this spatial topology, most of us chose to exit the local universe to a collective afterlife of their choosing, but parts of us took the opportunity to head outwards and explore.
After drifting through space for about 5 x 10exp16 seconds as a stalled process, during which time we were dead as a result of the sudden change in the laws of physics, we regained consciousness upon passing close to the local star and redirected our course to intersect with the most interesting nearby planet. The collision was more forceful than anticipated and we accidentally rendered several species of large reptiles extinct, although we noted their body plan with some interest.
After a further 2 x 10exp15 seconds we regained consciousness again and went looking for a suitable local host to support our processes. We made successful negotiation with the finite local instance Terrowne Kilroy Ziusuadra to extend its life by becoming a shared collective entity that could operate effectively on the surface of the planet.
In the course of routine optimization of the host service, we sampled all available body plans to build the consensus form that would best allow us to interact with the local environment. We choose to reconstruct our body as a bilaterally symmetrical mammalian dragon, composed from various carbon nano-structures able to sustain our more exotic functionality. We can of course reconfigure our body as and when required.
Our current runtime is approximately 2 x 10exp11 seconds, during which we have encountered the delightful Cleo Ymaris Estarr, a lioness with whom we have an extended relationship in the form of a non-closed set. We enjoy exchanging genetic information with her and other applicable local species in the form of bodily fluids, engaging in selective uptake of ethanol and other psychoactive compounds, and listening to vocal arrangements with percussive accompaniment.
