Talla is the holiest of the Settlements- it is unique, as the only settlement with two churches. One is located in a Quarterr of the settlement which is under the control of house Kronar, suggesting that they will be the Holiest of the Thresher Houses- maybe they have a custom where every family tithes their first born daughter to the Sororitas.
This will affect the distribution and background of the Sororitas forces, and the character of House Kronar. I figure that Cannoness Jahalla Athebraxis was born to House Kronar, and that the second Church was built with tithe and toil of Kronar to celebrate their daughter's ascension. This means that Athebraxis will be one of the family names that make up the clans of House Kronar. While Jahalla herself must, as the senior representative of the Sororitas, reside at the Cathedral in Aegis City, Talla would be the Settlement were Cannoness Veera Strife would be stationed.
Additionally, while the Ministorum would not want to concentrate their resources in a single settlement by stationing Missionary Mayhem in Talla, it is probable that he would be stationed in a settlement with Kronar Representation- likely the territory where the assets under Kronar control are most valuable.
