Well played; although you interpreted the clues incorrectly, and missed some! Let's reveal...
Kill the flower: In
this thread, Psyche thinks about killing Tamlin's mother, named Lotus; a type of flower.
or add it as a tattoo? reference to the red dunes which mark the base of her horn.
You came into existence on a beam of light; I told Boom last time, that I was always going to reference the player of the character. This is a reference to Rayo. :3
spoken of in four-part harmony by a questionable philosopher. : In Phaedo, Plato has Socrates give four arguments for the immortality of the soul and life after death following the separation of the soul from the body - this is the four. Many debate whether or not Socrates actually did and spoke the way Plato portrayed, hence the "questionable philosopher"
If there was a bible to describe the light that you see, it could be found in Romans chapter 16:21. The key here is IF; this wasn't a literal bible reference. This was a reference to the Aurora Basin. The name 'Aurora Borealis". Aurora comes from the ROMAN goddess; the name was coined in 1621.
But how could you think such random brutality is beautiful anyways? This follows from the Basin - the light is caused by the collision of energetic charged particles with atoms in the high altitude atmosphere; this is the random brutality, yet we perceive the light as being beautiful.
Luckily your muse has protected you.: Psyche has a deflection amulet that she attained from the post count - hence her MUSE, protecting her.
Thanks for playing kids. Until next time.
