Perseus's State of MInd
The fortifications of the city of Lilybee could not be said to be bad based on the time when it was built.
At a time when catapults did not exist, the almost two story high, two meters thick walls could indeed pose quite a significant threat to any attacking enemy if they were properly manned and garrisoned.
But unfortunately, this furthest port city of Tibias had been unable to keep up with the times.
Defenses that were once considered pretty decent now seemed to be lacking in luster.
It was because of this that even though one of the reasons why Perseus had come here was indeed due to the city's famed defenses, upon actually seeing the state of it for himself, he could not help but lampoon its deficiencies when compared with a city like Thesalie.
And even that city had fallen despite it being a few times bigger and there even being two walls instead of Lilybee's single one.
