I do also think it is going to have some connection to magic and lore, the mystery structure in this wks update picture also looks like a doorway to me. I think they will lead to different (small) areas where you can obtain items to be used for some form of magic. Possibly there will be related quests to gain entry and I daresay there will be elements of danger within, like some creature you will need to defeat to obtain said items.
The reason I think the thing everyone is calling a log pile is actually another door is ...

the centre part being a door, surrounded by what looks like some kind of rock or bone. I think the 'doorways' will possibly be biome connected, this one in the mountains, the first one in the forest.
The forest one leads to a fairy realm with druids that give items, pretty flowers with healing properties, fairy rings, ponds with lilies and magical fish, animals that will befriend you and ofc rainbows & unicorns.

Yeah, I did wonder that too after what Jorb said to Kaios, but doors have to lead somewhere ...
