If Mambatiyan was from malaiyur, Karuvayan was from Karimedu, Pandi was from Seevalaperi, where was Hiranyan from?

Vaatakudi.

The movie starring Murali was originally named Vaatakudi Iranyan. But Censor board objected saying it reminds of the real life gangster ( as if the other names didn't) So the producers dropped the Vaatakudi part.
