In the desert Ed had yet to name, in its city long since dead, Ed patrolled the empty streets with an inquisitive glance. The darkness of the night did not help hide any secrets.
That was because the ordinary houses of the city likely held no secrets. What they did do however was informing Ed about how exactly the elves used to live, and from what Ed managed to decipher thus far...
They lived comfortably. For example, the water channels that ran across the entire city were not for show. With a combination of arrays and just ingenuity, water was supplied to every house and could be acquired through faucets.
'It's always fascinating…' Across the world, multiple different people would come up with a similar solution to an identical problem using different means. The elves' faucet functioned very similarly to how faucets did in Ed's previous life.
