Oath of Honor (OoH) is a tricky card when dealing with movement. OL card's cannot trigger off this ability since the Knight doesn't gain movement points nor can traps be played since the card doesn't reference entering a space.
Basically, I'd have to say that with Syndrael's hero ability, if OoH was used, she's not considered to have moved (even though she does) and you can trigger her ability to gain the +2 stamina at the end of her turn.
Actually, oath of honor still triggers the "entering a space" condition.
Nathan has recently ruled it like this:
""It’s hard to give a umbrella rule for this, but a good rule of thumb is that if the figure was already on the map when it is placed/moved into a new space, that figure is entering that space. If you are not moving the figure from one space to another, but placing a figure that was not on the map, that figure is not entering that space."
