Macaroonia - Land of White Chocolate and Coconut
A floating, incorporeal evil humanoid cloaked in darkness
Early into session 5, while speaking with the ghost Xalandra, they are interrupted by a cloaked spirit-like creature. It emanates evil.
When it sees the the PCs, it unfolds a scroll. It reads, “I have been sent here on behalf of the Yuan-Ti. To those who slayed our brethren, M’Sorin of the house F’Sirin, know that we are coming to re-take the Temple and any who remain within will be wiped out without mercy. This is your only warning to leave. Decide. Now.”
The evil spirit takes out an hourglass, and says, “Be gone before the sands are emptied.”
