Weekly drop #15: spirits of the past

Hello there,

this week introduces new entities to the map: what I call "spirits of the past" - immaterial creatures who have witnessed history over the centuries. So they can share some first hand experience, much better than ancient monuments, etc. They will help me a lot telling the story in some more depth going forward. Now they're here, ideas are sprouting already on how I could diversify and improve on them :)

There's one other major addition coming up to reduce linearity in gameplay, but that is going to take more than a week, I'm afraid.
