In the latter case, holomorphic covering maps play a central role in determining correlators and are associated to Feynman diagrams. After recasting these maps in terms of the worldsheet twistor variables for ${\\rm AdS}_3$, we generalise to ${\\rm AdS}_5$. We propose stringy incidence relations and appropriate reality conditions for the twistor covering maps.
