Sam immediately let out his specters and souls along with his shadow undead out to spread as far as they can so that he could figure out the locations of the other players.
After some time, he did have a faint idea of where they are.
So, he took out a few recording crystals and recorded all the information he got.
He is the only one who had the means to obtain information through a soul search, so he is the only one that could provide the info.
Except for Dayus, he sent the info to everyone else.
Even if it appears a bit petty, Sam really didn't care. He didn't like the guy so he didn't bother giving the extra info out.
When the players received the information about their current situation they were dumbfounded.
The thing right now all seven players are actually dropped in the middle of a competition that they are completely unrelated to.
