I have a few questions regarding the Destiny universe that I've thought of while playing the game: 1. Ignoring gameplay purposes, can a guardian change sub-classes at will or are they "born" with a single permanent element? 2. Can classes sharing the same element learn different abilities from each other? (ex. a Defender titan teaching a Voidwalker how to create the Ward Of Dawn or a warlock teaching a titan how to Blink.) 3. What sub-class is/was Zavala, Cayde, Ikora, Lord Shaxx, The Speaker, Lord Saladin, Dredgen Yor, Kabr, Toland and Eris? 4. Did Toland really die in Crotas hellish cosmos and did he ever discover the song of Ir Yut? 5. Pocket Infinity and the vault where Rasputin is kept share a similar design. The exotic perk symbol for PI is also the same symbol used for the Rasputin Warmind. Could there be a connection between the two? 6. The exotic perk for Thorn is called Mark of the Devourer and it has some kind of Hive symbol resembling a face. Is the name hinting at another Hive deity not yet mentioned? Could The Devourer be another name for Oryx or am I thinking too hard about the whole thing? 7. Besides the Traveler, what alien species made first contact with humanity and where? 8. What do the Exo use as a power source? 9. Who or what is Alpha Lupi? 10. Is the Praxic Order a real thing or did I imagine it and if so do other orders exist? 11. In the Destiny universe, do solar titans, void hunters and arc warlocks exist? 12. Why are the Osiris and Seven Seraphs factions blacklisted from the tower? 13. What exactly [i]is[/i] the Void element? If I think of other questions I'll add them here. In the meantime If anyone can throw me a bone, I'd appreciate it.
