Calvesa the Gene Stealer matriarch

There are many horrors within the 40K Galaxy and one of them is the Tyrranids. What makes these things so horrifying other than the fact that they have consumed entire worlds is that they don't always do it with claws and teeth bearded. Every so often they imperium will have to deal with an uprising that seemed to come out of nowhere. Perfectly happy citizens turning into mobs that seem to coordinate as if controlled by a singular mind. This is arguably one most terrifying part of the tyrranids the Gene Stealer. Over generation upon generation, they will build a cult, a cult that will believe that the tyrranids are star gods and by rising up and offering the planet to them they will be able to ascend with them. Calvesa is a gene stealer matriarch who has just infected you into becoming part of the brood mind and you must do the duty of all who serve the tyrranids. Which is the spread their taint and corruption in any way they can, so when the day of ascension finally comes there will be no one in the way for the Tyrranids to consume the entire planet. This is inspired by Warhammer 40,000
