A Plane Curve Everywhere Equidistant from a Fixed Point

I have found
This round
An armament against

The cleft between
The temporal length of existence
And the inherent pledge to carry on

I've been the hopeful one
Guarding gratitude 
Like the last house
In line of wildfire

There is surety
In our elliptical birr
Just as the force
Of a strong wind

Removes the moment
Before it and redeems us
A forceful catch of breath
