You are correct.

The three heroes are Arthur/Artoria, representing the myth of the King in the Mountain (hope to be saved) and Blessing (she also provides the hero's appearance. Yes, this is an Iskandar-haired Saberface).

Representing Royalty is Iskandar, who provided a pedigree of heroic stories and inspiration through the tales of the Alexander Romance (a legendary account of Alexandar's quests, many of which were incorporated into this fictional hero's legends).

Representing Death, and the reality of the person who was defeating their enemies (albeit around eighty years late) is Genghis Khan.

Would you like me to reveal the true name and the rest of the information, or do you want to try and figure it out?
