LOTF Kyp, Kyle and Corran vs RoT Bane and DoE Zannah
RoT Bane (with orbalisks) and DoE Zannah are somehow transported to LOTF times in Naboo. In order to gather supplies, they raid a home and kill everyone but one, who turns out to be a Jedi. This Jedi warns the Council of these 2 sith, and Kyp, Kyle and Corran are sent to investigate. They find the 2 sith, and the encounter happens.
Remember that, since this isn't on Ambria, Zannah's sorcery won't be as powerful.
