Overview
Mistlands_Viaduct1 is a Valheim world location that spawns in the mistlands biome, identified internally as Mistlands_Viaduct1. World generation places up to 100 per world, with terrain constraints (delta 2-40, altitude -1 to 15), and an exclusion radius of 24m, which is why some seeds have far more of them than others. The data tags it as slope rotation and randomly damaged.
