Lore and Setting
Characters in Pandora disappear the same way when a player drops them out-of-character. Black cords sprout out of the ground, seize them, and drag them into the ground.
There are, however, a few exceptions. Language involved in spellcasting does not translate. Similarly, things that do not have a direct translation (such as Japanese honorifics) or that are proper nouns (such as the names of places, people, and items) do not necessarily translate.
Do characters from the same fandom recognize that a character in Pandora went missing in their world?
It is considered common knowledge that the sky is some sort of illusion, and mimics Earth’s sky, though this may be refuted by those with the ability to fly beyond Pandora's open ceiling. The sun moves across the sky during the day and the moon waxes and wanes like Earth’s moon. The constellations themselves are unlike anything seen on Earth, though.
Characters can still get sick and the passage of time can have a negative effect on their body (for example, a character can still starve to death). For characters that don't age, the lack of physical aging just saves them from conditions that normally come with physical aging.
