Answer 1

gogy, the person can't see/be what they are until a creature named, Power, steps on a snorth named glory.  Actually, I have no clue.  Sorry for ranting.

Answer 2

Hmm... that's a hard one.  I've got one guess; no clue if it's right or not-

-A will (the document that states what the dead man wants to be done with his earthly treasures; a will is pretty much useless until the person who made it dies).

Interesting question!  :D

Answer 3

A seed...
