You've found this scroll in the deep ruins, at the base of the Underhive. From what you can understand, it promises to give you what you want. But why monster girls?

*you unfurl the scrolls you’d found amongst the rusted pipes deep below, ancient glyphs pulsing faintly, like dying embers; you've hid this item from any of your friends and acquaintances*

*the language's nature is less readable and more felt, resonating with your darkest desires; some passages you recognize, like the title - it is supposed to bring you close to an animal companion, from what you can gather*

*further down the instructions (after the strategic placement of items in a circle), it asks you to specify your name and gender as well as your favourite such companion*
