Rachni Queen

Rachni Queens are the matriarchs of the hive-minded, insectoid rachni species. The largest of their species at about fifty feet long, queens are powerful and intelligent creatures who guide the soldiers and workers of their broods with a form of telepathic song, which also allows them to speak through "receptive" beings of other species. Queens also carry the genetic memory of their mothers, causing them to effectively be born with the collective knowledge of the previous hive.
