Сестра из теплицы

[J-Glob Phalanges]

Ava:
Our spirits liberated by devotion
The false sun's glitter will fade at last
We are neither stunned by midday desert splendor
Nor to the jewels our wills surrender, no;
We are dead for golden coin's sake.
And robed in silken moon rays we are dressed
By suns that shine at midnight we are blessed
And at the darkest hour... we are awake.

Death/Nameless is nice, but mainly because of the allure of entropy and absurdity; her ascension could be seen as uniquely non-creative/hopeless among the sisters and yourself.
