Yes, never trust by wrd of mouth. Always do the real research. To me the picture shows both sides, while one shows what looks like the primes were a reason of conflict, the other shows the opposite, that the Narakhans where the reason.
from what I can surmise these primes were obviously dragons who in mythology were the most renowned and powerful in the animal kingdom due to there thick scaly leathery hides that can repel magic, unimaginable size but amazing aerodynamics, and of course there fire breath, now when these creatures gained dominance for the sake of good I am guessing those who had different views of what is good rejected there so called powerful masters and from that point it's been a good old fashioned good vs. evil grudge match I am guessing these ones were either ones who were just tired of being bossed around or another creature of a different nature I would cast my vote on dinosaurs in that event because the whole " dinosaurs vs. dragons" gives of a certain Greek " Gods vs. titans" sort of thing if you agree (or not this is your story I'm just throwing opinions around) than just say nothing otherwise I will just enjoy the story as it goes which is easy because this is a really good story so far in fact I can't wait to see what happens next.
Ummm.... not really, dude. Kinda is how it looks on the actual image. Prime on the left, Narahkan on the right. But there is some complexity in the actual history!
