@KatieBear from what I could understand, there as an avalanche and the Emperor was buried underneath it.
The pope discovered her blood has a special quality that makes it turn into that red gem, she has also resolved that she will not run away and will face all the issues head on, to make her current life (and her loved ones) happy. Unfortunately, it seems that the God is making her forget <something> (not sure if it is her resolve or the discovery about her blood) until she gets back to the holy land (and presumably has finished the work she went to the mountains for).
Things with the demons are becoming more dire, we do not know yet if the Emperor has been found yet or not, or if the pope fainting is more serious than just for the cold.
