The Country Border

The border was a clear indication of the war between the two races. If the influence of the Kalki over the land increased, the border will move closer to the Treka Fort. And similarly, if their influence reduced, the border would move closer to their fort.

And at present, since the border was in the centre of the battlefield, it meant both sides were equally matched. Though, the two Elders knew that wasn't the case. Their land wasn't even completely theirs yet.

So, they had to first collate it and completely convert it into their land. Until then, staying put in a defensive war was in their best interests. And besides, their land was already massive and their population hadn't grown to the extent they felt the land was insufficient.

So, throughout history, the Kalki had never invaded. Though, the recent Raid into the land of the Treka was a first, showing that they too were capable of it when needed.
