# It is possible for a patron not to know their warlock

As you quote in your question:

>The Great Old One might be unaware of your existence 

And, as I assume you are aware based on your use of that quote:

>### Otherworldly Patron
>
>At 1st level, you have struck a bargain with an
otherworldly being of your choice: the Archfey, the
Fiend, or the Great Old One

Ergo you explicitly *can* have a patron who is unaware of your character's existence.
