Lime as wood
The wood: Lime wood is a soft wood that can be carved easily and very precisely. It is also light and flexible, allowing for easy transport and making it resistant to the strain of regular use. Thus lime wood is perfect to craft artefacts that will anchor complex
enchantments—or to give the illusion of complexity.
The magic: Generally 2 layers of runic diagrams are put into the wood: an internal one bioengineered at the cellular level, and an external one carved into the wood. Each can then anchor its own enchantment, either independently from each other or or interwoven into each other, thus adding another layer of complexity.
The magitech:
A lime tree is bioengineered and allowed to grow. It is then fallen and cut into planks on which enchanters can anchor their magic. This is perfect to make fancy furniture such as warded cabinets or tables that protect dishes against poisonings.
A bioengineered lime tree is grown directly in its final destination such as into the walls of a building. Its bark is stripped and it is sculpted and carved while being kept alive. A potion coating is added on top of it afterwards to give the tree the same protection as bark from parasites and infections. This allows the tree to continue to grow and the carvings—and the magic they anchor—to evolve with it. However, this requires a lot of long-term planning and so is more difficult and expensive.
A cheaper halfway technique is to cut a bioengineered lime tree into a plank but to keep it all along inside a potion that maintains it alive. It is then used to build a piece of furniture or a house wall and "replanted" into the ground to become an "alive furniture" or an "alive building". This means that it will continue to grow and evolve but in a more predictable way than as a full tree. It is however weaker and will not anchor as much magic.
Lime as fibres
The fibres: Bioengineered lime trees are striped of their bark before being used, thus wasting this material. To avoid this, a special use has been found for it: the bark is soaked in water for a month so as to allow for its inner fibres to be separated. The fibres are then weaved, and the resulting fabric can be used to anchor complex enchantments.
Warded clothes: Lime fibres have been great for developing a new type of
wards that can be attached to clothes keep them clean and to protect the wearer in a better fashion than with a portable warding artefact. However, this technique is extremely expensive, as bioengineering is not cheap and growing trees takes time, and so this type of clothes has become the mark of the imperial elites.
I really like that you have chosen lime as the tree of choice, rather than stereotypical oak or something. I love they use the bark fibres too.
Thanks :D I got the idea from fantastic mechanical sculptures made in Nantes. They said they're using lime wood because it's light, flexible and easy to carve and I thought that I got to make use of this XD
