Abstract
We discuss the open descendants of diagonal irrational orbifolds, starting from the case and analyzing six-dimensional and four-dimensional models. As recently argued, their consistency is linked to the presence of geometric discrete moduli. The different classes of open descendants, related to different resolutions of the fixed-point ambiguities, are distinguished by the number of geometric fixed points surviving the unoriented projection.
