Answer:
I am cracked by Indiana Jones. What am I?
Though blind as well, can lead the blind well.
I have a title and many pages I am a genteel of genteel descent I am a killer veteran of war I am a slave to my lord Pledged to his service.
I cost no money to use, or conscious effort to take part of. And as far as you can see, there is nothing to me. But without me, you are dead.
Though easy to spot, when allowed to plume, It is hard to see, when held in a room.
What is always coming but never arrives?
