Padm Puraan, p 119-120
Ikshwaaku's youngest son was very qualitative so he named him Dand and gave him the kingdom of Madhumatt between the two peaks of Vindhya Mountain. One spring, he met Shukraachaarya's daughter Arajaa and got attracted to her. He had her forcefully. Arajaa told everything to her father. Shukraachaarya cursed him that his everything would be destroyed and Indra would rain only dust for 7 days and 7 nights. Thus Dand's kingdom got destroyed within 1 year. Since then that place was called Dandak Van or Dandak Aranya.

* It seems that from Raam to Krishn there was only 15 generation time difference.
** There are two kings whose name was Nal  - one was the son of Veersen and the other was the son of Nishadh. This Nal was the one who married Damayantee and went in exile because of losing his kingdom in dice game with his brother Pushkar.
