The setting is a low-magic early-medieval fantasy period based on the witcher setting in terms of politics and meaning. The magical system is sympathy-based, similar to what's in the Name of the Wind, where magic-users can create sympathetic connections between things to cause effects.
The character is isekaied into this world, and ends up on the edge of the forest overlooking a recent battlefield. It looks a couple of days old, there are still some scavengers picking over the corpses but no armies are in sight. Crows wheel through the air and the stench of death is everywhere.
