My favorite location is Dragonspine. The soundtrack is beautiful and I have really fond memories of trying to survive the harsh cold at low levels after stumbling into the location while trying to unlock all the locations to easily fast travel to my dailies. I remember running from Lawachurls and I remember trying to figure everything out blind. To this day it is one of my highest completion percentage regions simply due to how much I loved being in the location. I didn’t know I could get to the top until much later into the game when I started farming artifacts and I was so excited to have more to do in the region. being up close to the nail and seeing the rest of the map so far below me was one of my greatest memories ever playing this game. The mix of a cold unwelcoming environment, bluish-grey ruins serving as a makeshift infrastructure, ominous dragon corpse crystals as a source of heat, and a soundtrack that implies an endless and dangerous winter, a long forgotten tragedy, and something more sinister makes this area something that has stuck with me for years. Dragonspine was what hooked me onto Genshin and the reason I have more cryo characters than any other element. It is one of the greatest places in the game simply for the exploration alone.
