Chitin glared at you for interrupting and replied "Well through magical system analysis, it has been proven that love is tied to the heart. So even though you lack a magical system, magic does not seem to ignore the fact that it was in the place of your heart. Magic that was formed from your own love. It had essentially cycled back to where it had originated from, but now actually magical. There, it rejoined your heart... which was in tatters, but because magic is the answer to most things, it was able to help repair your heart. Furthermore, seeing as the magic came from both of the queens, it now recognizes their magic as part of you. That is why the fire did not actually harm you."
