Obstacles have never been a problem for the evaniels.
They weren't just fast; they live in a completely different world where everything else is too slow for them. Most of the advanced species are similar to each other, but at the same time, completely different in terms of abilities.
But perhaps the most common trait of each of the Higher Races was their environment; specifically, their youth. How they grow up and how they were taught to move through life. As beings that held unimaginable powers, the Higher Races were living in a world that was too fragile for them.
For the evaniels, they learned how to adjust to everyone else's time; to perceive the moment as others perceive them. They were told to be patient, they were taught to wait. But of course, as beings of incredible speeds, it was their natural and primal instinct to want to break free.
You can't imprison an evaniel, they will become mad very soon and very fast.
