The Annuated, also known as The eldest of the Interior People and Their Progenitors are ancient Trill symbionts whose age ranges above 20,000 years old, living in the deepest part of the Caves of Mak'ala. The Annuated look similar in shape to their younger descendants, but are approximately 30 meters long and 8 meters in circumference. They also spout a number of tentacular projections along their lengths which emit bioplasmic discharges. They are bottom feeders who subsist on nutrient rich hot springs at the base of the Mak'ala cave network.
