Melancholia (sign)
The Melancholia was a symbol used by a faction within the Adeptus Mechanicus.[1]
It consisted of a parchment with the number four arranged in a four-by-four grid with all the numbers coming to the same answer, thirty-four. This symbol was used by those servants of Adept Koriel Zeth.[1]
Dalia Cythera noticed the parchment on the Mechanicum Protectors belonging to Adept Zeth and realized that she had seen the symbol in some books she had transcribed two years ago.[1]
