recently i have heard from a thread that it is possible that nitara's realm is zaterra. this would make sense as she knew lots about reptile and his people, and kahn did take over it. i decided to go a step further by saying that nitara and reptiles ralm could also be onaga's as well.
outworld was not originally a realm, just a big realm made up of small ones such as zaterra and edenia, before it was free. so where did onaga come from. we all asume that he was the first ruler of outworld so its possible that he created it. so i believe that onaga was unhappy about how zaterra was ruled and took for himself. it makes sense.
then i thought, how was kahn born and where? he was onaga's grand advisor, so he was probably recruited first, so he probably originated somewhere else. im thinking that kahn was born in chaosrealm and lived to create chaos until he heard that zaterra was going to war with onaga; who had now called the realm outworld. therefore, i think kahn joined onaga in hopes of expanding the chaos. then of course, he lead onaga's army into battle, killed reptiles ancestors and then got greedy and poisoned onaga. this explains everyones origin (b/c outworld was not created by the elder gods), and then explains why havik liked what kahn did. (he must have had allies and stuff in chaosrealm including havik.).

does anyone agree/disagree/have another theory?

it would also be cool b/c nitara freed zaterra in mkda, so if mk7 has a konquest where you go to all of the realms again, you could visit reppy, kham and cham.

and once again, it would explain why reptile thought that kahn dunit but wasnt sure, how kahn could have freed zaterra if he wanted to and how reppy could evolve back into his ninja form.
and it could be connected with why reppy was onagas host in mkd, but thats probably coincidence. and nitara did find a temple explaining reptiles people. i think it works perfectly. you?
