A grand return-- with a couple of riddles!

[His Wizardness]

A grand return comes with some grand questions. However, one riddle that I will be, I must confess will be not nearly as hard when it is written rather then said.

Here is the first question (no hints because you should be able to figure this out easier):

What lies in the green rolling valleys of the green glass door?

Another riddle that is more typical:

I am taller when I am young yet I am shorter as I age
Above all, a mere gust kills me.
Who am I?
