The Western Lands
The Siphai Guard, once the elite military knights of the Eastern Empire, now is a small force devoted to the Child Emperor. Most of their time is spent protecting the small corner of Tzi’Mar, the former royal palace, that the potentate spends his time in.
The average Siphai Guard is a highly trained killing machine: a truly elite soldier who fears neither magical nor mundane weapons. The knights of the Empire have largely dissolved, but can be found protecting cities, leading war bands, or bidding out their services as mercenaries and adventurers.
Although strictly regimented and disciplined, the knights were allowed great latitude in their choice of weaponry, and are versed in almost all modern weapons. Some use magic and ranged attacks while others focus on being in melee range. The only non-negotiable prerequisite is being truly above all other applicants in skill and capability. As Tieflings became more common, it became standard practice to exclude other races due to the racist assumption that they were not as capable.
