I'll have to interrupt there, as you can roleplay an escape attempt, but not a successful escape without giving others a chance to do something.
The spell you cast has an Intent of "protect", so it will protect its target, but it won't serve as an effective means to stop it. That would require a different Intent.
The inquisition guards were surprised by the spell, and the sudden appearance of what seemed to be a cage of bones surrounding them shocked and confused them. Only Brother Herox had received enough training to cope with an actual magical attack. He closed his eyes for a second, following the instructions he had received - to ignore and disbelief any effect and not let it control his mind. At the same moment he opened his eyes again, he made a step forward, testing the spell. He half expected to crash into the bones, half to be attacked by them, but they moved with him, like a shield or plate armour. He let out the air he had held back, and looked for the heretic - and spotted him just as he ran out the door.
Herox rushed after the heretic, his armour of bones barely fitting through the entrance door. Outside, he almost fell over another apparently drunken guy, he was standing near the entrance with his eyes close, making small noises like a rat. Herox ignored Zuno and followed Kalan. He knew the heretic could not run away far, as by this time of night the town gates would certainly be closed. As long as he let not slip him into a hideout, Herox would get him, sooner or later.
What to do with him when he got him, that was a question he could not yet answer. Without his guards, the brother had nothing to defend himself with should the heretic be aggressive. He hadn't thought this through, but did not yet realize that.
Inquisitor Lucious was finally ready. The Templars positioned strategically around him, close enough to defend him from any attack, but wide enough to not block his sight into any direction, he marched into town. He missed Kalan and Brother Herox by mere minutes.
