To avoid any kind of confrontation, Ender called all his subordinates after they finished packing the corpses of the magic beasts, and then explained.
"These two friends over here are young Gabriel and miss Priscila, they are travelers that have been training in the wilderness and ended up offering us help against the magic beasts that surrounded us, after Omar and his army took a detour to never be seen again".
Ender's subordinates started at each other, of course the previous was a blatant lie, because though they were too busy to witness Daimon killing Omar, they did get to see Sarah casually looting the corpses of Omar's subordinates before returning to Daimon's side.
