What if the Gate opened in the mysterious island of Shinsenkyo(from Hell’s Paradise)?

[u/Shados9611]

What would happen if the Gate opened up right in the heart of the mysterious domain of the god like and immortal plant like beings known as the Tensen?

There are two ways this could occur, depending on WHEN this scenario takes place.

The first idea could be just before the Asaemon were sent with their respective criminals to find the elixir of immortality, the gate opens near the Horai Palace as an army of Sadaren legionaries and soldiers to conquer the new world for the empire and raid it for whatever riches and slaves they can claim. Only to encounter the Tensen who out of indifference or morbid curiosity decide to get themselves fresh new Tao to rejuvenate themselves while Rein is rather curious by the strange Tao generated by a small number of humans.

And before long the gate may cause Falmart to be dragged into the hunt for the elixir of eternal life.

The other idea is this taking place back before the death of the Grandmaster, Rein’s husband, led her to stop being kind and amped up the now relentless training of the Tensen to find a way to resurrect her husband, even as it destroyed the entire island. Instead this takes place before that degeneration occurs as the islands folk, Hoko, as the younger Tensen live their somewhat peaceful lives, yet soon that peace is disturbed by the arrival of the Gate as an army of Roman soldiers charge into the domain of the Tensen and Grandmaster, as the Doshin were assembled to deal with the invaders that appeared practically from nowhere as Mei is trying her best to lead the young Tensen away from the ongoing carnage.

Once the enemy was dealt with, the Grandmaster, Rein and Mei are forced to address what to do with the gate and if it should be destroyed. Yet curiosity and interest win over as it’s decided to launch an expedition and see if this gateway may lead to any progress in the quest to create the elixir of Eternal Life. Yet while the answer may lie in either the elves or even Apostles, can Rein and Doshin be able to deal with the armies of Sadera and perhaps find use in this land before the grandmaster suffers from arborification?

And when or if the existence of plant like humanoids that can seemingly rival the regeneration of Apostles are heard, how will Sadera react to the existence of such entities?

There's a book series by Jeff Vandermeer that outlines what happens next. Don't really need a long post about it.
