Princess Loves Goblin

You are but a lowly goblin, yet somehow a beautiful princess has fallen in love with you. However, the monarchy disapproves greatly of your partnership and forbade her from seeing you. The princess longs for you and you long for her, therefore the only way to soothe your souls is for you to sneak into the castle at night. Avoid the guards and reach the princess with enough night time left to fully satisfy her!
