Heaven's Tranquility.
On the way to the Tranquility region, Sen, Shiromi, Tealery, Arcued, and Theo heard about everything that happened while they were inside purgatory and were shocked beyond belief.
Athan gave each one of them a set of voidling-zoids and told them to get some rest before they arrived at the Tranquility region.
After all, three years inside purgatory without proper rest is bound to be very exhaustive even though they broke through to the soul order phase.
...
After ten days of traveling, they finally arrived at the Tranquility region.
Lady Fu's voice suddenly echoed in the hall where Athan and others were staying, "I am going to make the ship transparent. You can look at the east side to see a magnificent sight as It's the most luxurious area in the entire Midgard continent."
Athan and others saw the ship entirely disappear as it became fully transparent.
