Funnily enough, Westmoor is one of the few realms on the continent that takes OI relatively seriously. In RP terms, Westmoor sees OI as one of closest traditional allies (this is one of the reasons why Westmoor never directly helped the SoA in the war in the peninsula - but there were also other reasons).
When all of the OI's new mainland regions revolted and switched control to Westmoor, the bulk of Westmoor's armies went into those regions to do civil work and police work to get the regions stable so they could be handed back to OI in good condition (as had been agreed between Realm Councils of both realms). Westmoor put a lot of effort into bringing the regions into a good state, and also partially rebuilt and fed Kazakh, before returning the regions to OI in a well organized way.
Westmoorian lords still sell food to Kazakh and Kalmar as needed (Westmoor tends to sell its surplus to its allies - pretty much as you'd expect).
