I was about to post about a potential vis source location and it occurred to me that a general topic might be useful. It might not. Maybe this will sink like a stone.
Some redundancy with established material is to be expected. There's a lot of Mythic Europe, a lot of material, and a lot of real Europe. My intent is to list real world locations and their suggested art association, but I suspect it will drift into generalized vis sources.
I'll list title, location, real location, suggested vis source, and a description of the site.
I won't suggest a quantity, as people have wildly different ideas on appropriate vis wealth.
The Waves of Navare
Real Location: Navare, Portugal
The waves at Navare are astoundingly large from October to April, and can peak at up to 65 to 100 feet, 20-30 meters. Probably a rich aquam vis source.
Navare is a small , unremarkable fishing village on the Atlantic Ocean with a stony coastal outcropping. Off short there is an underwater canyon which sometimes ejects a mighty water wave, usually about the time of a distant storm, which carries an impressive amount of vis with it, although the vis spreads into the ocean if not collected quickly. Collecting vis from a giant wave may prove quite a challenge.
Speculation: There may be an even richer, more stable, source of vis in the canyon. Capturing the vis before it ejects a wave may moderate the size of the waves.
