Operation Orion Phase One
Four cities, that was how many places the Beowolves needed to be in 3 days. If that wasn't enough, each city had a hurdle. A dragon in Shivan, a field that caused hallucination in Oliran, and a never-ending army in Aveda and Heliskina. This was not forgetting the demon lord class entity, Shota, that was looking for them.
Each city was spaced from each other over the land of Alfheim. In this regard, the elves were almost religious. Each city was exactly 4,100km away from one another. Thus baring the fortresses themselves, they needed to travel over 16,000 kilometers. Just by riding their Sleipnir bikes at 400 km per hour, they would need 41 hours of riding nonstop to cross the distance. That was not putting any time to eat, hunt, sleep, or fight the actual battles.
