The early Loroi were not great builders; during the ancient period the greatest works of the big city-states were mostly practical in nature: fortifications and defensive works, great harbors and lighthouses, great irrigation projects. The most famous great project of the ancient period on Deinar would be the fortifications built by the Eastern island nation of Daiam, who essentially ringed their whole territory with a network of walls and citadels, in an attempt to protect them from the rival nation of Nabolin.
Loroi would have been very impressed with human projects like the Great Pyramid, especially when told "it's just a tomb for one man."
In the Classical period on Deinar (iron age through pre-industrial), Menelos was the analogue of Rome, and sponsored many non-military projects, that could be compared to our Colossus, Great Library, and cultural buildings like Hagia Sophia/Notre Dame/Taj Mahal/Pantheon/Parthenon, most of which still exist in modern Menelos.

No and no.
