Natural and CICSPLEX

Natural Mainframe/CICS used and 8.2.3 level:

Detailed explanation of the problem: Can someone please explain to me how Natural operates in a CICSPLEX environment? Does the session remain in the same CICS address space where it started? Or can it “wander” from one CICS region to another (even on a different computer) with each (pseudo-conversational) enter? If so, how are the Natural threads maintained?
