It is impossible to get to Serpent's Hold without a boat or some magical shortcut, so it does not see the traffic that many other cities get.

It is a fine place to be a warrior, however. The Warrior's Guild has a hall there, along with a skilled weaponsmith shop and armoury. Everything that one could need before setting off on an adventure can be found on these two islands. Afterwards there are two talented healers for patching up any wounds.

The stables of Serpent's Hold are a good place to practice any animal-related skills that might need honing.

Constructed on the largest island just east and south of the Cape of Heroes, the Isle of Deeds, Serpent's Hold is the training grounds for nearly all of the realm's fighting population. Serpent's Hold is a single, compound structure, with an internal castle to house the Lord, Captains, and instructors, meetings halls, and mess hall.
Outside of that, but within the keep's walls, are the barracks, the smithy, the stables, and the training grounds. The walls are of large stone set with mortar, similar to a generic French keep of the "Middle Ages."

Serpent's Hold is less a city than it is a stronghold. Although the keep has been there for some time, very few buildings have sprung up around it. The land is not particularly favorable for farming or hunting, so no one has come to the keep seeking protection. In addition, most of the soldiers move on once they've completed their training, so the only non-warriors who have taken up residence in the area are those who can provide for the Hold's needs, such as blacksmiths, tanners, etc.
