Just upping and leaving (with [i]no[/i] time-jump) would be technically feasible, a massive time-jump like that ... really wouldn't. Just imagine if you try to time-jump to two weeks forward, but then three days into the two weeks, the entire city they supposedly stayed in gets razed to the ground by the other branch! The Zerul City people are about 6-7 hours in the future compared to Aemoten/Thaler/Etakar, who are currently the ones supposed to meet them.
