Avalonia finds this acceptable.
As farmers of Avalonian descent in Avalonia's Eastern frontier interact more and more with the locals, they find them very pleasant and as a whole, not dissimilar to the populations of the surrounding nations. Trade becomes prominent in the region, and as a result of all this, Avalonia proposes to Espul that with the area's general permission, the lands be annexed by the two nations to form a universally beneficial situation rendering the locals in no way subject to foreign attack, and Avalonia and Espul in possession of more lands.
