I figured out how Mr. Kelly was able to field Njal and a Rune Priest with JOWW. Page 64 of the codex says "Special Characters" are the exception to these. Thus you could field Njal and a RP with JOWW, but not 4 RPs with JOWW. Page 81 is as clear as air on no 2 can have either the same saga, powers, or wargear.
