The ideas are interesting, but we already have a concept for a composite artifact, and a level 5 spell as well.

In general, the concept of the city, as such, is fully ready; all that remains is its technical implementation. All elements of the concept are very closely tied to the historical and cultural aspects of the fishfolk race, so introducing various ideas, even if they are interesting, seems quite difficult due to their detachment from the main conceptual line. However, we will still implement some of the ideas proposed here.
