Sea Giants are the most common breed of giant in the The Thousand Isles. The Sea Giants are approximately 17 feet tall, tremendously strong and skilled sailors. They are also known to be tremendous swimmers, capable of covering leagues of sea by swimming alone and diving deep beneath it's surface. "Sea Giants seem to be slightly below average in intelligence, though possessing of a low cunning.
These giants are organized socially in clans, or small kingdoms, of which there seem to be many in Gianthome. Up until recently these kingdoms constantly feuded with one another and possessed little in the way of advanced metallurgy or shipbuilding skills.
Recently, giant longships of new and superior construction have been seen throughout the The Northern Reach, raiding and pillaging outlying settlements. Even more disturbingly, the giants are now in possession of cannon and firearms, admittedly of primitive design but making up for it in their gargantuan size.
