The Pact of Dressiden was often considered to be the conclusion of the Ahnmes-Leighu alliance that had dictated the political landscape of Ednia over three decades. The assassination of the former head of House Ahnmes, Cassius O. Ahnmes, by his brother-in-law, Jyn Leighu, also brought an abrupt end to more than two decades of Ednia's militant foreign policy towards the Nations of Yashu. The infighting over succeeding the household title severely crippled the influence of House Ahnmes over the rising houses of merchant nobles, whose interest lies in the construction of roads and bridges near the border to facilitate the exchange of wheat for timber and precious metals, which were abundant in Yashu territory. With the death of Cassius, the Western Campaign against the Nations of Yashu never came to fruition, which allowed the progressive moderates to take control of the aftermath. The equipment and resources prepared for the Third Western Campaign were taken advantages by the merchant nobles, notably House Glijja and House Miles, to lay down the foundation for what would later become the Crystal Trail. Shu Miles, the head of House Miles, led the rise of the progressive moderates in the Council of the States and put forth sets of rather radical foreign policy at the time, those which later would make Ednia an economic powerhouse on the continent. House Leighu did not openly support the expeditions proposed by the progressive moderates, but it was widely believed that the head of House Leighu facilitated the transfer of equipment and resources from Dressiden.

On a side note, due to Jyn's suicide following the assassination, the motive behind the act was never elucidated. While Cassius's political rivals are numerous, he is too formidable of a state man to succumb to his political enemy. Even with all their combined powers, the struggle would still be a mismatch. Though Cassius took concubines, Jyu Ahnmes, older sister to Jyn, was well-respected and in good relation with the rest of House Ahnmes. For many from House Leighu, the act of assassination was a shock because Jyn was often regarded as a well-mannered and kind young man, even though eccentric and quiet at times. However, Jyn did spend a year near the Yashu border during his time of service and might have developed some sympathy towards the Yashu'n from personal experience of fairly frequent harasses by the corrupted boarder patrols and greedy merchants. At this time, the record is incomplete and would require some further analysis.

Furthermore, from disclosure of private sources as well as records in the Ednia Military Academy, Jyn was a part of a small survey squad that decided to embark on an expedition to uncharted mountain region west of Cymeblin as part their graduation thesis. By presenting the cartographical data for a significant amount of territory between Cymeblin and Lake Letra, all members of the survey squad eventually graduated the Academy with the highest distinction. Considering the geographic details in their map and the fact that the squad returned to their outpost headquarter ahead of the schedule, the efficiency of their teamwork was rather extraordinary. Since the Cymeblin territory was historically Yashu until the end of the sixth century, it is likely that the team had a local guide, possibly of Yashu descent. Interestingly, the report did not mention the existence of a guide and was particularly vague on some deviations from the original expedition route. While the private sources seemed to skit around the truth, the lack of contact with locals in the final report arose suspicions. There were a few days' worth record that read rather artificial and generic, contrasting the rigorously detailed descriptions in earlier and later sections of the report. The difference in style was especially noticeable when the team was exploring areas around Lake Letra before their departure returning to the outpost headquarter. As of now, something seemed amiss, yet no records could pinpoint the conflicts.
