Ellen I had another conversation with it just now, it confirms the brazilian spelling "Exu" seems good, would be interested to know its reaction if you asked about that. Ps, ask it about Exu, and the other yoruban spirits, its fascinating stuff - it all looks very closely related to ancient technology, they have something called an "Opele", which happens to be a kind of fortune telling system, based on 256 possible outcomes - does that ring any bells?
