Harper thought for a second. "Hmm...I think the safest thing to do is send Sebek in. Once the coast seems clear, he can come back and ferry us across like you suggested." Harper gave Jake a thumbs up. "Don't worry, we are almost experts in this kind of situation. Even if things go wrong, a little Cofagrigus here and there won't stop us." 
Looking up to his flygon, Harper signaled him in and Sebek went on his way. Sebek flew quietly and carefully, looking between the sarcophaguses, ceiling and walls for anything suspicious. It wasn't until he reached the end of the hall that the Cofagrigus sprung to life and set their eyes on the two trainers.
