Memory is an elephant who drinks information from the world. She has only one purpose: to archive the experiences of conscious beings. Every being coming to her planet leaves an impact in the water. When it rains, Memory drinks ponds and puddles to encode in herself the information contained in the water. She is rather serene and relaxed because she feels at peace with her mission. Her usefulness is clear and she pities Hope, which, as a more abstract concept, suffers as he struggles to remain himself.
At the end of her life, saturated with information, she gives birth to her successor and dies. The new Memory buries its mother's body to store the information it contains and erects a gravestone. It's this cycle that produces Memory's cemetery, the place in which Infini's main menu is situated.
