Answer:
The shorter I am the bigger I am.
A dragons tooth in a mortals hand I kill I maim I divide the land.
I am a cave full of bones and the house of a worm.
What is the beginning of eternity the end of time and space the beginning of every end and the end of every race?
I am the outstretched fingers that seize and hold the wind. Wisdom flows from me in other hands. Upon me are sweet dreams dreamt my merest touch brings laughter.
If itβs information you seek, come and see me. If itβs pairs of letters you need, I have consecutively three. What am I?
