Every time you do some kind of complex magic there is some portion of the energy that will get released in other ways ... as light, as heat, as a shockwave. Teleportation of one person over a short distance is already a fairly complicated and energy-intensive thing. Teleporting eight people across many kilometers, like seen here, requires an amount of energy and control that only a Gena backed up by several very experienced and powerful mages could muster.
Making sure that the process is free of any harmful side-effects for their surroundings would be even harder ... but it would certainly be possible to do.
Of course you would have to care enough for that to make the extra effort. Which Ki'i'Mar obviously doesn't.
