Alrescha, I really hope that someone else could give you more clues...in the meantime, Ill just copy from a horary tutorial what kind of things do Sagittarius and Virgo ( Moon co-significator in Virgo) rule, maybe they ring a bell or something
Indoors, Virgo rules " the south wall, following a meandering line, closets,
pantries, study rooms, bookcases, desks, dispensaries, home offices, rooms
that are rented out in the house, and rooms kept locked for precautionary
reasons" .
Indoors, Sag. rules " upper rooms, the larger ones in the house and one
where a safe is kept or where ammunition is stored. Sagittarius rules army
barracks and the southeast wall" .
In terms of where to look for it - we have a fire sign = near heat sources, partitions of a house, near iron or walls, East direction + earth sign = near/under the pavement or floor, near clay or mud
, on the ground; South direction.
Both Sag and Virgo are mutable = places near water sources, closets, covered places, rooms within rooms, antechambers. Interestingly, the Moon is in the 9th house, which is in analogy with the Sagittarius sign, where Saturn is - I would also suggest looking near religious items/artworks depicting ceremonies/rituals, anything connected to voyages abroad, long journeys, explorers, parades, science, education, publishing, dreams and visions, mysticism (like documentaries, books, posters, photos, an encyclopedia, or anything else you can think of), legal documents/insurance policies. Hope this helps a bit more ( dont turn your home into a mess this time
take your time cos after all, "tomorrow is another day"
)
