At the centre stood a massive tower, a dozen times the height of a grown man. It was tall, overlooking everything within and beyond the Meka Clan. The warrior pointed at it with a smile, "This is our destination. Our Clan shaman is waiting for you inside."
The tower had arms on it, positioned around half its height, like bridges that extended to the houses around it, casting a net. They were arched in such a way that their weight would be fully borne by the pillars that formed the houses. Moreover, it created a path for people to traverse, from the central tower to the terrace of the houses.
As the terraces of all the houses were connected, it created a cohesive ring that acted as a fortress of sorts, easy to defend but hard to conquer. And, the height of the houses wasn't impossible for the warriors to jump from, since the landing area outside was made from sand, cushioning their fall.
