Iṃgor asked his familiar, an oversized mole, to follow Sapphire underground. The familiar's senses won't allow accurate tracking, but it should still be good enough to get back into the tracking spell's range. However, before he followed, he had to bring back the ingredients he purchased, otherwise they would slow him down. He sped up, but didn't start running, as he didn't want to attract too much attention, especially from the guards. He didn't want to be slowed down unneccessarily.
Back in the hideout he just quickly deposited the items so no vermin or rodent could quickly get to them, and sprinted eastwards once he was done. He chose the path through the back alleys and 'hidden' roads. He definetly didn't want to be stopped for anything now.
