Abstract
We provide, through the framework of extended geometry, a geometrisation of
the duality symmetries appearing in magical supergravities. A new ingredient is
the general formulation of extended geometry with structure group of non-split
real form. A simple diagrammatic rule for solving the section constraint by
inspection of the Satake diagram is derived.
