It's dangerous to go alone!
"It's dangerous to go alone! Take this." is a quotation from the 1986 video game The Legend of Zelda. It is spoken by an unnamed old man, whom the player can meet in a cave at the beginning of the game; he gives the player character Link a sword to aid his quest to defeat Ganon and rescue Princess Zelda.
