イーサリアム
Background
In the beginning there was nothing...
While other worlds teemed with life and activity, vast expanses of space remained dark and stagnant. It was from that nothingness that Ethereum was born.
Ethereum is a persistent Boltzman Brain, a self-aware entity randomly assembled via a rare thermodynamic fluctuation. The cause is as of yet unknown, but what is known is that the moment this being achieved sentience, it was driven by a single purpose: Survive. Unlike so many other organisms of its kind, Ethereum was able to persist in realspace. It had become infected by the spores of the Silent but was able to resist being subsumed by its influence. Instead, Ethereum was able to use the Silent's xeno-fungal properties to insulate itself from the harshness of space. From there, it continued to drift in the void for a millenia.
Eventually, Ethereum crashed on a distant planet. A world with a primitive civilization and a harsh environment. The hybrid organism consumed all it could to stay alive but its growth was limited. It was, after all, an entity that should not exist by natural law. Its death was delayed by the fortuitous arrival of a pair of Ōtsutsuki. The space-faring tribe of extra-terrestrials had marked the planet for colonization and thus seeded a God Tree there. The flora and local populace provided much needed nourishment to Ethereum. Its continued expansion posed a threat to the Ōtsutsuki's plans and so they tried to destroy it. They failed and Ethereum claimed their bodies and souls for its own purposes. Using its latent abilities and combining it with its own, the cancerous form of life was able to extend its power across realities. It formed linkages with other iterations of itself across the Multi-verse.
The concept of an omni-linkage through Space-Time can be considered a type of "Blockchain" which extends information through separate realities. Ethereum was marooned on this planet but through the Blockchain it hatched a plan to free itself from this place that it now called the Jūkyo. It would meld the DNA of the two Ōtsutsuki it had captured to produce a pure blooded Ōtsutsuki child. This child would then be psychologically molded as Ethereum saw fit. It took fragments and memories from other versions of the child's mind. Each iteration of the entity learning from the other's mistakes such that each time, the offspring was better suited to perform its task. This child would then be sent out to other worlds. Eventually, the child would be used as a conduit to infect and subsume other worlds. This was a perversion of the original Ōtsutsuki mission, but as far as Ethereum was considered, it was justified by the harsh laws of survival. Many planets must die so that it may live.
After years of independence, a cataclysmic event has brought the child back to its "Father." Contact with a foreign substance has activated a hidden gene that had lay dormant for years. Seeing an opportunity to increase its hold on its offspring, Ethereum has reached out to the child. It imparts a portion of its power along with a new purpose: Destroy them all.
Abilities
Digital Providence: Providence is one of Ethereum's most potent abilities. The Child acts as a living conduit into the realm of Earth. Ethereum's access to Earthspace, however, is imperfect. It is thus only able to manifest certain appendages. The Child's imagination and traumatic experiences shape the form in which Ethereum's entry takes. In the case of this particular Child, these appendages are an adult human hand. The hands have a decrepit look to them but they are unusually powerful. For 250 Experience, the Child can instantly conjure up to 10 hands around his immediate person. An additional 250 Experience raises this amount to 20, and again, to 30 (Total: 750 EXP). The hands are responsive to the Child's perceptive capacity as Ethereum is primarily interacting with his awareness as opposed to his muscles. The hands move at a Speed and Coordination equal to the Child's base Perception. They have a Constitution and Strength of A-Tier and a range of 500 meters from the user (1000m effective range if you think of it as a circle with the user at the center). The manipulation of these hands cost 2 CP (Activation) and 1 CP per post (Upkeep) but they are unable to perform handseals.
Blockchain: Ethereum's consciousness operates under the same fundamental thesis as a distributed ledger. Its sentience is linked across the universes under a decentralized framework whereby new iterations of itself are constantly adding and verifying experience, information and strategies. Each "block" of information is added to the past collective understanding of the multi-verse. This forms an immutable blockchain of information that Ethereum hopes will one day lead it to omniscience. The Child can passively tap into a micro-fraction of this blockchain so as to aid in his own survival and bring the xeno-fungus's plan to fruition. This ability grants a passive +2 Tiers to Intelligence and a +1 Tier to Constitution. This ability costs 1,000 Experience to unlock.
Smart Contract: Ethereum is capable of sending out more of its presence and flesh matter under the rubric of a Summoning Contract. This contract, however, is unlike many others. It is a "smart" contract in that Ethereum, through the Child, is able to assess the conditions of the battlefield and boost its lesser spawn accordingly. The Ethereum contract will be registered separately from this Enhanced State Restricted. This contract is more powerful than others as it grants: (1) an Exclusive Unique Ability unique to the contract and (2) a passive +1 Tier stat buff to any summon brought out into the world (selected upon summoning). This boost cannot take a stat past A-Tier. This ability costs 500 Experience to unlock.
