For your sake I hope it was because of a Spriggan because if it isn't it could be an early sign of a rather nasty bug where everything normally peaceful to you becomes hostile (guards, villagers, deer, elk, foxes etc.).So I have like 250+ hours into the game now on my first playthrough and for the first time .. ever .. a fox ran up to me and attacked me. It was unprovoked. Anyone else had this happen? Really odd as foxes always just run away from my experience.
Yeh, Spriggans. I've been attacked by deer and goats who seem to have a faint green glow. I assume they are influenced by the Sprigs. Maybe the smaller fox didn't exhibit the green so well?
