[@ Abagworo] you shold know that ngwa migret from an area withing imo state if there was a relation between ngwa and nri it should be withing that place they came from before setlling in opualangwa but for the founders of present day opualangwa from where ngwa communities trace their origin, during that period that has to do with the foundetion of opualangwa it was foundend in a way that it has nothing to do with nri/eze nri.Opualangwa was foundend in form of a community which is madeup of village setllment that is diveded into family known as onumara, each onumara has it's owen gethring/assembly know as nnadi when all nnadi comes together it becomes amaala and also in ngwa land they will first of all count and recognize their nnadi and amaala this two will come first before any other like Eze nri/others.

This ezeagu and his Eze nri igbo story well i'm from obi ngwa LGA in abia state, in ngwa land we dont know any body or king callde Eze nri those that might know about him will be any one who have read text books that talks about igbo history. In ngaw the gudian/keeper of our culture is divided among number of familes that make up a particuler village each family have their groupins know as nnadi when this nnadi comes together they become what is know as amala so ezeagu like chinennye said which is also true about ngaw people inwhich there is nothing like ozo/nze stuff in ngwa land ,the prisent day Eze's in ngwa land is a borrowed cultuer from anambara area which happend during the colonia era and this Eze's are only a ceremonial head the power behind authority in ngwa land is run and control by amala so ezeagu this your story of igbo traviling to nri for one thing or the other in the olden days i dont think that such happend in ngwa land of igbo.
