In the never ending quest to get elves to live in trees, I am taking things one step further and attempting to get the entire city in a tree. Magic is not in the equation. The tree would start out looking like this from above:
As time goes on, the tree would expand outwards, with the dual trunk marked 'roots' remaining in place while the circle grows. The city is within the circle, as shown.
You can think of it as people living in a hallowed out tree trunk, with one very large exception: the 'trunk' is only located in the area marked 'roots.' The circle part is basically one gigantic root, about as thick as a two story house. It would like this, from the side:
Is this design possible? Is there any reason trees like this would ever exist? This is for a fantasy novel, so you can make a few things up like creatures if necessary. My idea is that the tree creates a safe haven for animals (and people) within the circle, and then gets a lot of nutrients from them.
Details (as requested by Lord Dust)
- While tree shaping is not entirely out of the equation, I would prefer not to use it, as it takes a long time and is therefore impracticable for immediate housing purposes.
- The elves are human-sized, maybe six inches higher.
- The city needs to be able to accommodate around 5000 people. I've never really thought about it, so that estimate is flexible. It is a capitol though. (Think really big community instead of city).
- The tree does not need to be of any particular type.
- The city is located on the edge of a forest, at the foot of a mountain (about 3000 meters high, little to no snow). The entire area would be at about 50˚ North. It is sitting on mostly plains-type ground, used to fog from a nearby forest river. Probably generally moist ground, though it dries out in the summer, reaching temperatures of around 80-90˚F.
- The tree should be one of many. This is not mandatory, but would be quite useful.
- As for modifications, certainly it can be modified. The main thing is that it has to be found more or less habitable (meaning the circle is in place). - Certainly tree growing can occur later, just not to start.
- It doesn't have to be a tree, but it does have to be as tall as one, as I am envisaging it overshading at least part of the city.
- The tree was found at its current size. It is however alive and growing, though likely very slowly. (Speed is flexible.)
