So, a Youtuber called
Shoky actually managed to decode/translate the Eldoran letters on the screen/ interface used by Freddie for contacting & summoning DiVERS during his
stream.
From that translation, we know that the teleporter is called the "Incarnation System" and it materialized Hiroto & co in the flesh/organic body that can bleed. That means May also has an organic body while in Eldora which is something that I believe have not been experienced by other EL Divers before her, not even Sarah.
That's some really interesting bits of trivia.
