WMG: Fire Emblem Tellius  "Chris" is Ike, and Soren is "Mark".
Chris is rather similar to Ike (though moreso to FE9 Ike), and
we never see Mark's face. Soren and Ike left Tellius, got split
up, and now Ike is helping people out because that's just how he
is, while Soren is partly trying to make himself a rep so he can
get better answers from nobles and the like about Ike's
whereabouts, partly repaying Lyn for saving his life. Would also
explain why the Tactician/Mark doesn't do any more tactics after
becoming known. As for the supposed sinking/flooding
Yune/Ashunera caused, I think it's more likely it simply raised
water levels around Tellius (since Ike seems to head for other
continents at the end). This theory would put Tellius and Elibe
in the same universe as Archaneia, Jugdral, and Valencia. And I
kind of already believe Magvel and Elibe to be part of the same
universe.   • Fire Emblem Awakening confirms all of the FE games
to take place in the same 'verse, but Chris and Mark are most
likely not Ike and
