Ruined Silver City

After much searching, you finally discover the location from the vision. At first, it appears to be an ordinary-looking abandoned city. The silver disc and your water staff then begin to emit a radiant glow, revealing a shimmering barrier around the city. Curiously, you attempt to touch the barrier, but your hand passes right through. You step through the barrier and find yourself within a small, silver city, lying in ruins. Among the tattered remains is a mostly intact watchtower off in the distance. You rush towards it, hoping to unravel the mystery before you. Inside the watchtower, you discover a note inscribed in the same ancient language as the silver disc. This time however, you are able to decipher its meaning. The note speaks of how the city was under threat due to the ancient conflict, and that preserving the secrecy of their people’s knowledge was of utmost importance. To this end, the inhabitants chose to evacuate and retreat to a larger city in the south. The end of the note is strange, it appears to be some sort of poem. You can’t shake the feeling that it is more than mere poetry, so you translate it and put it into your bag.
