Florem Mortem, or "Flower of Death" in Latin, is a plant associated with Pedri Nanezgani. It was favored by his wife, Wrathia, and it grew on the planet she chose to build her empire. Its leaves can be smoked, a habit possessed by Wrathia and Odin. When smoked by the Vengess, it acts as a relaxant.
Odin smoked Florem Mortem, due to the effect it had on Pedri, which made him unable to speak to him; reason may be because it had a resemblance to how Wrathia did when they were alive.
It is both Wrathia and Odin's favorite flower.
It is grown on the world that Wrathia built her palace.
Odin keeps petals of the flower in a hole carved into his book.
