A Dentatsuna the Automata's interstellar temple and place of residence. As a fundamentally religious species, the Automata engineered large cosmic vehicles destined to act as both modes of transport / residential ships, as well as catalysts for the spread of their ARK Simulation.
In order to expand the simulation to a sufficiently large area, a Dentatsuna typically travels for a bit over 4.4E+6 Sol years. It houses a single generation of high-level Automata, and maintains an active ecosystem of low-level maintenance Automata.
Once the ARK Simulation of a given Dentatsuna is of sufficient size, the ship is abandoned in a remote location, and its residents enter the simulation. In some instances, the Dentatsuna's chosen location of abandonment allows for its maintenance ecosystem of low-level Automata to persist in their duties. This results in ships continuing their maintenance cycle indefinitely, producing eerie megastructures of perfect cleanliness in otherwise desolate environments.
