Please, dear developers, add some kind of decorative device that would emit a ray of magical energy into the sky to a great height (up to space). So that its color would be determined by a large gem inserted into it, and the part where the light comes from would glow like an activated stand with an eternia crystal. I also ask you to add the ability to build and install various ground and ceiling stalactites, like those that we meet on the surface and in caves/dungeons. Or maybe giant crystals that would be collected from a pile of crystal shards.
