What is novelai gift keys?

As an AI language model, I do not have information about novelty gift keys. However, gift keys are commonly used in gaming to give access to a specific game or DLC (downloadable content) as a gift to someone. These keys can often be purchased through online retailers or game developers. The recipient of the gift key can activate it on their preferred platform (such as Steam, Xbox, PlayStation) to gain access to the game or DLC. It is important to ensure that the gift key is compatible with the recipient's platform before purchasing. Some game developers also offer special limited edition or collector's edition gift keys that may come with additional content or bonuses.
