Nandhipurathu nayaki's heroine is Kundavai. Other characters of PS in this novel are Arulmozhivarman, vanathi, vandiyaDevan,chinna pazhuvettirayar and her daughter, sembiyanmadevi, madurantagan, boothivikrama kesari,parthibendran, sambuvarayar, anurithar, ravidasan, parameswaran. The list may include other characters also. I have read 2 bagams of nandhipurathunayaki. I am in search of the third bagam. This novel is by vikraman.
The novels 'RajaRajan Sabadham' and 'Vandiyadevan Vaal' have PS characters and are continuation of nandhipurathu nayaki. I am not very sure about the order.The author of these both novels is Vikraman.
The novel "Vengayin maindhan" by Akilan also has some PS characters and it deals about Rajendrachola's conquests.
The next novel is "Gangapuri kaavalan" by same vikraman has few PS characters, which deals with the purpose behind the construction of gangaikondacholapuram temple and Rajendrachola's life.
There is also other novel by vikraman "Chola Illavarasan Kanavu". This i think is about the establishment of later cholas' rule in tamilnadu after pandiyas.
There is one more novel called "Rajadittan sabadham" by vikraman.
But i think, the last two novels are based on chola period before sundarachola. So i doubt the presence of important PS characters in that.
