Janus-faced, she sits in her
Sinister bathing tub
Cleansing herself from
Fallen lovers

The very ones
She devised subtle ends to
Lest they should claim
Her heart for a kingdom

Vandals of her plumage
Whom she allowed
To drink from her stream
Once or twice

A god of vengeance sent her 
A message in a bottle today
To prove the origin of her flow
And remind her that time is 

Fly-by-night

Evanescent Queen

**Aha!**

**That's it!**

**This answer may stick!!**

**And it's!!**
