Military action
The Face Wars, also known as the Wars of Yhivan Unification, or The (first?) Gun Wars, were a series of conflicts in the Gisha Delta that ultimately saw the Yhivan city states united under the Salamandas dynasty, and also included the conquest of several Ropog settlements, notably Kairn and Illen.
The Salamandas dynasty, under exarch Amato Salamandas, began investing in brass dragons, a type of hand cannon, and was quickly able to incorporate them in their armies. The heavy armor that had become common in Adellonian warfare since the The Adellonian Mysterectomy Campaign was practically worthless against firearms, and Yhivi Yon-Gisha quckly quickly conquered and consolidated power over the entire delta, establishing themselves one of the primary powers in the Post-Convulsive era.
