Aftermath
Immediate aftermath: The borders of the empire were redrawn to incorporate the newly conquered regions. For the first time ever, Arboise and Sanne now share a border. Given the past, this situation is of course unbearable. Everyone understands that the new peace is only temporary and that, despite all the nice words being pronounced, war will resume soon.
In the interim—flying vehicles: During the war, Sanne got hold of the stolen cuttings of the bioengineered plants. In the decade since, they have been able to use them to develop their own flying vehicles and to incorporate them into their army.
In the interim—other magitechs: While Arboise might have lost its major technological advantage, it is still the one with the best bioengineered plants and fungi and so the most efficient magitech. The current imperial drive to convert artefact handcrafting into mass production is also allowing the empire to put higher quality artefacts into the hands of rank and file soldiers. This is why all Arboisiens were convinced that the next war would finally let them crush the Sanniens.
Latest development: The Sanniens have just kidnapped the Arboisian
emperor from beyond the
wards of his own
imperial palace through means unknown. This is creating political turmoil inside the empire, with the government and the
emperor's soulmates fighting over whether to sacrifice the emperor and select a new one or to save him at a high political cost. Everyone is also worried over the secret new technology the Sanniens have used to get through the wards of the palace and the advantage this will give them in the upcoming conflict. For the first time, the Arboisiens fear being defeated...
To be fair to the Sannians, I would be quite nervous being neighbours with an empire that covers most of the world and would do everything I could to gain some advantage. XD

Especially if whatever new advantage they used to get through the wards of the imperial palace just happened to fall into their hands :p It would be way too tempting to just say no to this! Thanks for your comment <3
