Draining the "River" Part 3 of 3.

So beside the river banks you have trotted,
and inside the muddiest waters tread,
now what have you of the next things said?

There exist places of virtue amongst even the direst trickery,
and reconstructions and purgings.

The unnatural rivers in this vicinity dry.
And onto the purest form of flow
does this water now reside.

Colliding waves and derivative sands,
from the banks of the western and eastern,
to the banks of the norther and southern lands.

On forth I wander, my deeds now done.
If another I find myself crossing,
considering it of a million, one.

And then I will simply use fire,
to burn the grotesque place.
For they can keep their grubby water,
and barely will I care.

I gave what I could to the cause of purity,
for hidden schemes are now boring.
