Blood of Elf and Holy Grail

Illiterate half-elf wakes up and is kicked out of home Are you not allowed to go home until you find your lover? Do illiterate people want to go to university? Do you want to reach heaven with the blood of elves? What does the Holy Grail have to do with the elves who don't know where they come from? I just want to ask the boss: "Is there water? Is wine also acceptable?"
