Eliseos, or Elysium
Eliseos is just Elysium in Spanish. I chose the Spanish version simply because domains related to other forms (elysium, elysian, elysion, etc.) are all registered. (Actually I use to own elysion.tech, but
.tech is hardly recognizable.)
According to wikipedia:
Elysium or the Elysian Fields (Ancient Greek: Ἠλύσιον πεδίον, Ēlýsion pedíon) is a conception of the afterlife that developed over time and was maintained by some Greek religious and philosophical sects and cults.
I first encountered this notion in the animation "Saint Seiya". I'm using it to represent an ultimate website that can be used for profound mental communications (languages, knowledge, etc.) between humans.
