The Crystal Paladin

What if Allura and Coran aren't the only two alteans who awake from the cryo-freeze King Alfor put them in, what if it was also Allura's older brother Lancelyn.....What if Lancelyn was the original paladin of a lion who has been missing for 10,000 years......What if Lancelyn was stronger than the gods.... What if the only way for them to save the universe was to find the Crystal lion.
