WHAT AM I RIDDLES

My first is a creature whose breeding is unclear. My second, a price you must pay. My whole can be found in the river of Time and refers to events of today. What am I?

Marking mortal privation, when firmly in place. An enduring summation, inscribed in my face.

What am I?

When I'm used, I'm useless, once offered, soon rejected. In desperation oft expressed, the intended not protected.

What am I?

You can use me to stop,

You take me to smoke;

Not only do I stop, But I am a stop,

And the result of pool's first stroke.

What am I?

I'm a word that's hardly there. Take away my start, and I'm an herbal flair. What am I?

I'm one of five, I'm not alive. The one who sent me forth became king, The one who received me died.

What am I?

Many-manned scud-thumper, Maker of worn wood, Shrub-ruster, Sky-mocker, Rave! Portly pusher, Wind-slave.

What am I?

I can come in a can,

I can come as a punch,

I can come as a win,

You can eat me for lunch.

What am I?

What can be heard and caught but never seen?
