To know the insight of mahabharat epic period

Its really good to know more unpopular stories after reading quite few threads. I want to get clarification of my doubt in this forum [which is a bit out of MB main story line]. In Ramayana, there are many incidents depicted around entire India [especially south] , but in MB south is totally neglected. My question : Is the period matches the one mentioned in thiruvilayadal puranam [Lord shiva puranam] where the south ruled by goddess Parvathi [alias Meenakshi] and Lord Sundareswarar.

Hope to get a good insights of the epic period.

Ramya

Do you mean Devika?

In this starbharat, Arjun while fights with indra says that he was a devotee of Lord Karthikeya. Is it true [ I have not heard before]?

I heard that Arjun prays to Lord Shiva and gets the pashupatastra in south. Is there any evidence for it?
