I belive Olver is Gaidal Cain Reborn. Throw out all that Uno bull. Now my theory will be kinda vauge since the books Im drawing info from have fallen apart and been trashed by my family members. If i remember correctly Moggy was captured in a "vacuole" and didnt know when it might be cause the vacuoles kinda floats along the pattern so time is disstorted. Now if Cain left somewhere time is distorted (T'A'R) in something that distorts time (a vacuole) then it seems reasonable a ugly little boy could be the reincarnation of an ugly man.
