To write a compelling lore, there are several guidelines that you should keep in mind. Firstly, use concise and punctual language to convey your ideas effectively. Secondly, it's recommended to utilize positive assertions rather than negations to maintain a positive tone throughout the lore. Additionally, incorporating descriptive, qualitative, or colorful words can make the lore more engaging and immersive. Using present tense to create a sense of immediacy is also recommended. Furthermore, it's important to repeat specific names or titles frequently and cross-reference whenever possible to ensure clarity and avoid confusion. Finally, limit your lore to one paragraph at a 200 GPT-3 token per-lore budget.

With these guidelines in mind, the first lore I want you to write about is the ruins of a seemingly endless dungeon with a powerful spellbook hidden away, knwon as the Book of Netherbane.
