Parthibendra Pallavan's character has a unique armor in this film - made of scaled leather, shiny and much like a snake's scaly skin. Perhaps, this is an indication of the Pallavas' mythical link to the "Nagas" in history.

The Chola war elephants in the final battle have their tusks sawed off and fitted with swords instead.. This was common in medieval South/SE Asian warfare.

The line, "Look at another Chola prince who dies atop an elephant", alludes to Rajaraja's Granduncle 'Rajaditya' at the Rastrakutas' hands. (Battle of Takkolam)

This happened again to Rajendra's son in Western Chalukya lands (Karnataka), Rajadhiraja who was hence called, "Yanaimel thunjiya thevar" (Lord who died atop an elephant).

Banas, the chief of whom is said to be Vallavarayan Vandhiyathevan, were not confirmed to be the origin of Vandhiyathevan in history. In fact, Sundara Chozhan's grandfather, the first Parantaka Chozhan had uprooted Bana chieftains in the Karnataka/Andhra border with Tamilnadu.. So, the fiction here might have been to indicate how inclusive Chozha society evolved to be in its Golden Age. (In Sundara Chozha's time, one of the leaders of the Sri Lankan expedition was his brother-in-law, a Bana chief)

Eating the betel-leaf/paan snack out of the palm is an act of submission, as in the scene of Nandhini and Parthibendra Pallavan. The same was a part of negotiation with a Sultanate and the Vijayanagar emperor in history.
