1. I read in a previous Lore Question thread that one can become an Oracle later in life, does that mean that Oracles don't have the ability to see the future from birth?
2. If Oracles 'unlock' their power, does the age vary amongst individuals?
3. Does a human have to have Oracle heritage to become an Oracle later in life?

I hope that I worded this properly for you to answer, if I need to revise or reword anything please let me know!
