Maria and Rose {Mpreg}

There are two tribes, one called Maria, the other known as Rose. Both equal in power, both have an equal amount of members.

However when the two omegan children of the Maria tribe become of age, they will have to be bred to take over the others tribes.

Levi meets Eren, the soon to be pack leader, Mikasa meets Armin, the strongest warrior in the Rose tribe. Levi will help Eren rule Rose and Armin will help guide the Maria tribe.

Many trials come their way, the threat of war, people panicking and counting on them as well as being pressured to produce offspring.

{I can assure you this came into my head randomly because there aren't too many omegaverse tribe fics around, so I didn't copy anyone. But sorry if this fic is similar.}
