Alpha Lupi has been suggested to be a long line of people, a group or clan, if you will. Ana Bray ha been suggested to be part of this group and her relative too, Clovis Bray. Alpha Lupi is a position that only one person can have, lore wise. There may be an Alpa Lupi in the Destiny universe but we don't know who it is and we all just wear the crest. Alpha Lupi stands for First Wolf and this is why the Hunter Crest suggests YOU, the actual wearer is the Wolf. No one else. And why the Titan Crest suggests a group of people, rather than a single individual. The Dreams Of Alpha Lupi is alittle bit trickier. There are theories that they're poetry made from previous battles and adventures and encounters from different First Wolves through time but my personal theory is that they're actual visons the Alpha Lupi would get, either in their sleep or throughout the day and each would record these dreams and these recordings would be the Dreams of Alpha Lupi,
