The "Koyil Adhikarikal", or "Al/Ala Koyil", was the Chera royal prince appointed to individual chiefdoms, responsible for collecting regular dues — such as the and
arantai — on behalf of the Chera Perumal at Mahodayapuram. The managers of the four prominent
Nambudiri-Brahmin temples around Kodungallur, collectively known as the "Nalu Thali", likely functioned as the Chera Perumal's permanent council or ministers. The Ayiram ("The Thousand") served as the Chera Perumal's personal guard, composed of a thousand Nair warriors who acted as the king’s "Companions of Honour" and were also tasked with managing and protecting the
Kodungallur Bhagavathy Temple. The Padai-nayakar (or nayakan or Padai-nair) was the commander of the armed militia, either for the kingdom as a whole or for individual chiefdoms. Each chiefdom maintained its own militia known as The Hundred (Nutruvar), an armed contingent whose size was often indicated by the number of households within the nadu that could contribute fighters. The Nizhal ("The Shadow") formed the personal protection guard of the udaiyavar chiefs, serving them as loyal "Companions of Honour". Supporting the chiefs further was the Prakrithi, a body of non-Brahmin notables who assisted in administration. Lastly, the Adhikarar were temple or royal functionaries responsible for local administration, including the collection of dues and arbitration of disputes. == Major chieftaincies ==
