In the movie "Deivam', Thevar used his artistic licence to twist a fact, to accommodate his favourite idol. Explain.

'Deivam' was about the Arupadai veedu of lord Muruga. It had one story for each padaiveedu. Marudhamalai Murugan was thevar's favourite god. But it is not one of the 6 padaiveedus. So he replaced Pazhamudhir Cholai with Marudhamalai.
