Query: Flavour Violating Axions   I review the physics case for flavour violating axions. In particular, I
argue that relaxing the assumption of the universality of the Peccei-Quinn
current opens up new pathways, including: the relaxation of the Supernova bound
on the axion mass, a possible connection with the Standard Model flavour puzzle
and the experimental opportunity of discovering the axion via flavoured axion
searches.
