Castle Kwenaya was the long-time baronial seat of Barony Huinesoron, until his departure to take control of the former Barony Araeph. He still retains title to the castle, and Kwenaya still holds a vast collection of arms and armour from those knights who have departed Plort, or fallen in battle. Before he goes to war, Baron Huinesoron often pays a visit to Kwenaya, and bears the weapons and shields found there into battle, in memory and honour of the lost.

Castle staff include the warden Terri, the hunter Rosalind, and the messengers Sandra and Freckles, though the latter two also serve in the Baron's new castle.
