Riddles part 2

As promised, this is the other half of the ancient scroll from the Shadow of Amn.

1. At night I come without being fetched, at day I am gone without being stolen.

2. No beginning. No end. I am a symbol of the world's cycles.

3. Two brothers we are, great burdens we bear, all day we are bitterly pressed; Yet this I will say- we are full all the day and empty when we go to rest.

4. Item in the plane, you swallow me; Yet were I more, I could swallow you.

5. I have seen the moutains rise. I have seen the fall of Netheril. You shall die but still shall I march on.

6. To those within the dungeon I am joy. To those fully beneath my gaze, I can be hell.

7. I will save your life but yet can you die by me. I will settle disputes yet not with words.

8. Name me and so shall you break me.

9. Always do I tell the truth yet cannot speak. Look to me and see what really is.

10. I have 2 heads but one body. The more I stand still the faster I run.

11. Try to defeat me but try in vain. When I win I end your pain.
