Sarafan Templars were an enemy class that featured in Legacy of Kain: Defiance. They were the most "accomplished soldiers" of the Sarafan classes seen in Defiance and were seen predominantly in Kain's early chapters at the Sarafan Stronghold and the Pillars of Nosgoth.
Sarafan Templars wielded two handed claymores (although they could be wielded with one hand)and a uniform with metallic looking armor and red clothing underneath. The Templars were highly trained and skilled in combat and were the only one of the Sarafan ranks in Defiance that was able to block attacks. They were fairly resilient and had fairly powerful attacks but lacked any ranged or charging attacks (generally meaning they were of a lower immediate priority in combat than other Sarafan classes such as Inquisitors, Archers and Zealots; though their skill put the above Crusaders).
Much of Kain's Defiance journey in Nosgoth's early history actually takes place some years after the conclusion of Soul Reaver 2 (hence a new Malek statue in the Sarafan Stronghold Coutryard), it is therefore possible that the 'Templar' rank was created in interim.
The uniform of the Templars could possibly be inspired by the Sarafan Raziel's color theme which was red and he also used a claymore.
