We actually have no evidence that Chakravartin created Naraka, and we are likewise unsure on whether he created the whole universe or just Gaia, because he recurrently refers only to "world" which can mean bunch of things.
Moreover, the process of death and reincarnation kept working even after his demise, just like the general Samsara and the wheel of life and death, which have obviously kept going after his defeat.
Chakravartin himselt may have fallen victim of this process, as a little spider is seen in the post credit.
To keep it short, there's no clear cut indication that he has created anything on a 3-A scale, and Naraka itself is more akin to a metaphysical world rather than a real one.
