Mostly comprised of foreigners, mercenaries, criminals and other 'undesirables', the Southern Frontier Defense Force operate in small units.
Often used for undercover or dangerous missions when the Temple Guards are either unavailable or unsuited to the task, the HSFDF, as it is sometimes known, also serves as support for the main Harmonian Army during military actions as well as for reconnaissance activities.
The Southern Frontier Defense Force is normally stationed at the Harmonian frontier town of Caleria. There are at least 14 units within the HSFDF each containing approximately five or six members. Unit's expenses are monitored meticulously by superiors.
