Now, maybe a small poem to lead the way ?

Ahoy Space cats of all horizons!
I found a strange letter by my doorstep this morning, supposedly it'd open the doors of some foreign domains. Ah, who cares?
Puzzles am i right?!
It reads:

Within nebulous haze, the demoness sways,
Her crimson eyes, a glowing blaze.
With predatory grin and voice in swarth,
She lures the lost with whispered warmth.

With nefarious whispers, the demon misled,
Amid covert plots, she shaped his dread.
Her titanic will bound him in chains,
A defiant pawn in dark domains.

He met a queen, auguste and fair,
Yet thwarted dreams obscured his glare.
Through agonized trials, he withstood the fight,
With unshaken alacrity, he reached her height.

By potent will, her curse was slain,
And cupid’s grace broke love’s refrain.
Through iron storms, he carved his fate,
With kryptic strength, defied his state.

In balanced peace, his heart held true,
As modest hands claimed love anew.
With serene joy, his soul took flight,
And fragrant dawn embraced the night.

There was a note too:
Oh, and I should tell you that only the start holds sway, that gold lies within those lines and probably that only duos shapes the way.
Whatever that means.

This gibberish eludes me, perhaps you, space cat, might find the way forward ?

I tried my hand at a SGTool protection, I hope i did not mess it up. All games are level2+ and the GA runs until the 30/03 3:30pm ( too many 3s).
I got inspired by the many puzzles that appeared recently, thank you SG, you're great!

Oh, and as always, GL space cats! 🍀
