Mass Effect Part Eighteen: Rachni

All but extinct the Rachni are almost a complete mystery. Little trouble was taken to understand them, and no quarter given during the Rachni wars. The queen is at the centre of a hive mind, held together by singing. They are capable of ship-building and FTL travel and despite other limitatons are a fierce and implacable foe when roused.
