This is ridiculous, you think. He's just an old man, and he's not even using the map!
'I need this,' you say. 'I'm sorry, but I must have it.'
The old man glares at you. 'Ignorant beast!' he spits. 'You think you can just take it? You're no better than the rest of them! The map is a fake. No one has mapped the Maze of Triumphs - surely you know that?'
You ignore his petty remarks and leave the room, the map safely in your hand. You're confident that it's not a fake.
Outside in the corridor, you consult the map. It says that the room to your right contains a magic fountain that makes the drinker immune to battle wounds!
