  We describe global embeddings of fractional D3 branes at orientifolded
singularities in type IIB flux compactifications. We present an explicit
Calabi-Yau example where the chiral visible sector lives on a local
orientifolded quiver while non-perturbative effects, $\alpha'$ corrections and
a T-brane hidden sector lead to full closed string moduli stabilisation in a de
Sitter vacuum. The same model can also successfully give rise to inflation
driven by a del Pezzo divisor. Our model represents the first explicit
Calabi-Yau example featuring both an inflationary and a chiral visible sector.
