Rick Riordan said this quote
“ Doors vurst open all along the walls, and skeletal warriors marched in, hundreds of them, from every time period and nation in Western civilization. They lined the perimeter of the room, blocking the exits.Hades bellowed, Do you think I want war godling?I wanted to say, 'Well, these guys don't look like peace activists'. But I thought that might be a dangerous answer. ”
