Missives of Courtship from the Abyss

A bundle of texts found in Agnes Marshcradler's hut. Seemingly love letters of affection written in ancient Abyssal to the hag.
Three scrolls of parchment found, all written in the same scrawl and calligraphy.
== Parchment 1 ==
My dearest Agnes,Abandonment and betrayal, two words that shall never be uttered from your lips when you speak of me. For your beauty, loyalty and love can never be outdone. Never will your affection be spurned as it has by the archfey of Tornka Forest. You have given me your passion, and in return you have mine.Your Prince.
== Parchment 2 ==
My dearest Agnes,It brings me joy and pride to know that you are with me for eternity. Together, we shall restore the Forests of Tornka to a rightful ruler. My dearest shall be more, she shall be everything, a patron and Queen in her own right. The forests are ruled by pretender gods. But soon, they shall fall under the hands of the Archfey, Agnes Marshcradler. I promise you this.Your Fiend of the Heart.
== Parchment 3 ==
Our time is nigh, my Queen.One released, a second soon to pass, a third to be found and the fourth lost to the pests of the South. One is compelling, two are tyrannical but three are unstoppable. It is only a matter of time before our brother Oni brother is found and released from his chains. Continue your good work, my sweet Agnes. Find our brother and all will be ours, your wretched pact shall be broken and your ascendance assured.V.
