"Ha…" Artemis let out a breath. After the amount of vampires that she was forced to kill, she was exhausted. Her bright body had already dimmed down, which means that the serum had done its job already, and that it was time for her to face the side effects. Luckily, she had managed to clear out all of the threats…
Artemis did not wait for the effect to occur, however. She didn't even rest properly, and left towards the location where she had told Mark to go to, not even a second after letting out a breath. Her idea was to rest and calm down her breaths while walking, which she did, and which was a success.
Surprisingly, there were no signs of side effects, or at least, that's what Artemis thought. There were no changes to her body, and she felt pretty fine.
'Maybe the effects appear after a few days.' She figured, since she didn't want to be too optimistic with her thoughts.
