The Mother Entity is Species 9341's pendant of a Starbase and a Tier 1 Yard. It produces Entities on a very high rate. It has no other defensive properties, although this was probably never the intention (see the campaign bug in the Extermination mission on the matter). This station cannot be built by conventional means, as there is no constructor for this faction. It is only part of the single-player campaign and may be part of custom maps.
