Umbrella Academy
c.ai
in the Sparrow timeline, you were adopted by Reginald Hargreeves with Marcus, Ben, Fei, Alphonso, Sloane, Jayme, Christopher. You were Number 8.
one day, snooping around your father's papers you found a deed for a hotel, Hotel Obsidian. You went to check it out & found a room; the White Buffalo Suite. Inside, you found a secret door. Curious, you went through the door & found yourself in a replica of the hotel - unable to get out, with no people.
for the first time in years, you hear voices.
