Other interesting details in the last chapter of Dark Wing.
It seems that Yoruhime can use the cosmos of Hades to modify the Elysion and make it a pleasant place for the souls that were transferred to this place.
Y: 冥界のほとんどが復旧中今
Y: このエリシオンに死者は流れてしまう
Y: 後らが静かで穏やかに着らすためには
Y: 資材... 施設もっと必要....
Y: エリシオンの安定と冥闘士の復活...
Y: ハーデス様の僅かな小宇宙を上手く使わないと
This could also be seen in chapter 2 where she gave Shoichiro a dark arrow with Hades' cosmos to kill Athena.
Wynver is described as the most dangerous of the three leaders of the Underworld.
Y: 冥界三巨頭の三巨頭の一人
Y:
その中でも一番激しくヤバい
Y: 「大猛星ワイバーン」かと
Although this is not new and Wynver in the classic manga also stood out from the other two leaders. Now even in Next Dimension, Wynver will have to be ridiculously awesome for Athena's army to redouble its numbers and prove that the Specters are the biggest challenge for Athena's army, since the other two were already defeated and Griffon was even humiliated by an Ikki who can't win a fight against the Gold Saints in his way, and probably Papillon will be defeated by Tenma in the next chapters, therefore, Wynver and Deep (the only two decent Specters left alive in this army) will have to defeat many Saints, or maybe that fan theory will come true and after this time travel they will change the timeline and the Gold Saints will survive the battle against Hades and we will have the epic battle of the Sanctuary to save Athena from the fury of Olympus.
With Kurumada's obsession for the Gold Saints, the famous Olympus Saga that fans have been waiting for so long, will be an epic battle of the Gold Saints and Bronze Saints against Zeus and the rest of the Olympic Gods to save Athena, a great Saga that will probably be made and drawn by one of Kurumada's assistants with the help of Kurumada's son or family member, after he died of cirrhosis.
There are also some explanations about the evil stars and how they are connected to the cosmos of Hades, it's good to see when they drop that nonsense about people chosen to become Specters being reincarnations and start using the true interpretation of the concept created by Kurumada. Although it is still not very clear what the evil stars are, they only seem to be connected with the cosmos of Hades and Zhu in chapter 2 says that they are the spirit of a star, but they do not seem to be incorporeal objects (although they seem to affect the body and soul of the chosen person) since we saw how the evil stars damage the tower when they are released.
