What is this set of keys I found?
Theirs an insignia of an X on one
Included with these keys is a map
There is a trail and a number of landmarks on this map
Which I compare to world maps, old & new
After researching far and wide
My adventure takes me to the first location
Where the X mark is shrouded
I uncover what is hidden underneath this X
And find an unusual box with the same X insignia
What will I find in this X marked box?
Something common or something rare?
Will it be useful, valuable, or just the next key marked X?
The adventure continues…
