You are a young man named Robert. As part of a field trip, you and your friend Patrick traveled to the trade hub port town of Saphril's Museum of Marine Archeology, an institution that is highly lauded due to the high funding that the town's long-held connection to the Church of Poseidon has granted it, which allows it to be a center of learning for the city. Anyway, as your class, yourself included, is exploring the building and gazing at its various exhibits, which hold artifacts sourced from the region's earliest days of human/monster habitation, to just before modern times, each of you are invited by the Sea Bishop attendant who is guiding you to attempt to pull what appears to be a very ancient, yet very real sword from within a large mass of long-dead coral; the sea strata looking as though it were forcibly pulled from the ocean floor by the hand of an angry goddess, rather than the smooth block of matter that a person typically imagines. One by one, each person including the faculty makes an attempt. To be clear, despite or perhaps because of the incredibly deep connections the museum and its staff have with the Church of Poseidon, with all of its staff members being mid-high tier clergy members of the church in question, none of them expect any of you to be able to remove the sword from its place; the activity is just meant to be an opportunity for people to take thematically appropriate pictures, and for archeologists and similarly scholarly-inclined people to study a piece of history that it would be otherwise impossible for them to encounter. When your turn comes, you pull at the ancient weapon like all the others and don't expect anything to come of it, but the sword begins to be removed from the "stone", and rather than let go of what is, in the end, a piece of museum property and arguably a holy relic, perhaps due to an instinctual contraction of your muscles as a combination of adrenaline and surprise, you finish releasing the sword from its ancient vigil. Once you do so, as you gather from exclamations of surprise/fear let out by museum staff near windows, the weather rapidly changes into that of a fierce storm, though the museum itself is unaffected, and a divine and markedly female, voice exclaims in deep surprise and ~satisfaction~ that after hundreds of thousands failures from the beginings of humanity to modern times, she never expected any man to be able to pull the sword from the "stone" and defeat her challenge.
Apparently, rather than being a test of physical strength, the sword could only be removed by someone who fit certain predetermined criteria, with the ones in this case being not those required to be a good king, as you had assumed, but the man worthy of being Lady Poseidon's groom. . . Yes, the mighty sword that is strewn with symbols of the ocean and in-laden with enough gold and fine material to finance several kingdoms was a wedding ring.
Now that the scene and its players have been laid out, what happens next? Although a broad scene has been laid down, are there any details that you would like to include? Any complications from a teenager on the verge of adulthood releasing what was apparently a divine artifact? Do the museum staff react in an especially notable fashion,and most of all, what does Lady Poseidon do, and What Do You do?
