Looking at such Elise, she has surprising strength. Because she also took lessons from the church’s templars in things like handling weapons, she is far more powerful in that area than a novice adventurer.
At the very least she should be able to protect her own body by herself.
Otherwise she couldn’t expect to be allowed entering the party either.
And, the templars, that she left previously, are simply put guards established for the protection of the church.
Since they aren’t attached to the kingdom, it is officially correct to call them guards rather than a Knight Order, but with the motive of protecting the church, that yields authority being appointed as state religion, there is a tacit consent allowing them to be called a Knight Order.
