Master Riddlers!

Congratulations to Logistics, Krypton, and Greys, winners of the Year 600 Master Riddles! Each was awarded a prize of his choosing from the fabled artefact vault... and here are the riddles they solved!

Riddle the First:
My patrons walk all over me,
My landlord runs around on me,
And nearly drowned me once, you see,
No thanks to errant reverie!

I've suffered from inconstancy
In basic ideology
But I must say, most modestly,
I'm proud of my autonomy.

What is my name?

Riddle the Second:
One became three; to one came another three, after two.
Three became one; the one that's left is me. Who am I?

Riddle the Third:
I am born of the sewer, but I am no vermin.
Possessed by a fallen trickster, oft clawed by mighty talons,
My song is also sung by the cradle of the giants.
To what was made and broken, none can refer
Whilst I roost upon my fickle perch. What am I?
