Neo-nanos

Abilities
Contrarily to the nanos, the neo-nanos do not require a connection to a great computer (And thus to the network of the Halo). They are a complex assembly of nano, which allows them to make decisions on their own. This being said, they have the ability to connect to the network. But although the small factories used to build them have been repurposed from factories building the nanos, and have the necessary hardware to connect with the network through the Factories, this connection ability is switched off at the Factory level. Such connection has just not been established for security [Secrecy] reasons.

The Nanos are designeds as prestablished machines much closer to the usual idea of nano-technology. Therefore, they have a greater intellect at creation and can be programmed to independantly heal a body by repairing the telomers, fighting diseases and promoting healing (beyond the humanely possible). Unfortunately, this comes with some caveats, such as a stop to the female reproductive cycle.

They are also very sensitive to the body's electromagnetic field. Thus, they are inert when created, diffusing in the body of those who ingest them and being gradually filtered out by the body, and they activate only in an electromagnetically silent organism (dead), through a high voltage electric shock. They will then repair the body and maintain it in the exact same condition to the best of their ability.

The connecting of the neo-nanos to the Network allows for some kind of imperfect summoning, in which the summoned cannot interact directly on the environment, as the neo-nanos are not ubiquitous and adaptable enough to do anything but heal bodies.

They also degrade a lot faster than nano as they cannot reshape themselves, and end up being ejected as a bluish-white mineral deposit.

On the Convoy
The Neo-nano were created on E3a. They were not in existence at the time of the Convoy.

On E3a
They are only present in the Valley of the Gods, where they are kept secret from the rest of the Branches.

The Networking ability has been switched of at the Factory level.

On Ithria
They are present in the Valley of the Gods, as well as in the small pocket of the Bone Court of Essirah.

The networking ability has been scrambled by the many storms and the Factories could now technically connect to the network if one of the people that has Neo-nano in their body was to request it, which is what will happen, first with Corbin, in an accidental way, and then with El, through the impulse of Yli.
