Even Clifford structures are natural generalizations of Quaternionic Manifolds, when the structure is parallel they contain Quaternion Kahler and Kahler geometries as particular cases. In this talk we will explain how to construct the twistor space of a Manifold with even Clifford structure. We talk about the geometry of this space together with other fibrations that form a diamond diagram which is a generalization of the Quaternionic diamond in the work of Boyer and Galicki. Many interesting properties arise giving Kahler Einstein, Sasaki Einstien and Special Kahler Geometries which we will explain.
