Like a flying arrow shot from a powerful bow, Adhara pierces through the forest with ease.
Now she was already inside the territory of the Dark Elves, and the sentries scattered across the forest were nowhere to be seen. Adhara can conclude from this that the Dark Elves were also hit hard by the awakening of the Executor.
Since they were quite a high-rank Supernatural race, many of them should have a Slave Mark.
Naela doesn't seem to be affected by the Executor's awakening probably due to her young age for a Dark Elf. On top of that, she comes from one of the noble families which means that she might be well protected and pampered by them.
From Flunra's explanation, only Supernaturals that exceed the killing threshold were branded.
