"Here we see Marrie. 'Marrie' refers not to any individual creature, but rather a hive collection based off the archetype displayed in this figure. Innumerable eggs are created and gestated and held in reserve, but very few individual examples can be found actively seeking from day to day."

"Marrie likes to 'play'. It will seek out an interesting party and curiously involve itself with them to varied degrees. Despite its slightly dangerous appearance, the creatures initial explorations tend to be fairly benign in nature...."

"....However, should it find a suitable individual the insect will expend itself within the person. It will fuse its carapace to a convenient location and release the entirety of its internal composition into the blood stream. Massive, conventionally irreversable transformations result. The specific configuration that results varies from person to person, but generally falls into three categories for various purposes - Queens for producing eggs, workers for extending Marrie's habitat, and rarely a warrior archetype is produced throughout periods where extermination efforts are carried out against the species. Absorbtion into the hive generally includes the recipients personality and memories, however this varies as well. Some individuals clearly retain minor to a large measure of their former self - however, loyalty to its new order seems to always be assured in any captured specimen.
Individual base archetypes appear to be capable of imitating the result form from any captured and assimilated creature it has reconstructed in the past. The constructs are short lived, infertile and considerably weaker than the original converts. "
