'To the Spirit:
Your language is really hard to learn. I have learned a small part from the books you gave me. I am now writing this letter to you, and you can understand it...'
Why are the words they don't know spelled out in Pinyin? This immersion is a bit too intense.
Magic was reading this letter. Fureyas could understand the books from the Spirit, so most players would buy one or two books for their Fureyas to read, which could also increase the probability of Fureyas receiving permanent and temporary blessings.
The Spirit NPC shop also sold some peculiar books, like "Introduction to Spirit Language," which fell into this category of books.
He had also bought his Fureya this book because she had previously written him a letter, but even then, the grammar and wording were only slightly better than a grade schooler's.
