Eisen pushed the finished lock into the wooden door. He pushed the corresponding metal key into its and turned it around, watching as it properly locked into place. With a smile, he pulled on the handle, noticed that it didn't budge, and quickly unlocked the door again. Now that this worked, he was able to quickly move on to the main protective enchantments on the building.
The main issue with something at this scale was that any gaps that were in regular structures were also a lot larger now. Eisen had to account for any sagging at the hinges that could happen over time, and also had to make sure that if the wood expanded or shrank due to the temperature and weather nothing would end up breaking, so these natural gaps were really unavoidable. And these gaps would make it very easy for people to break in, which was why Eisen would create an enchantment that would prevent this.
