Koalinth (the name is both singular and plural) are marine goblinoids closely related to surface-dwelling hobgoblins. They stand about 6-1/2 feet tall, with sleek, muscular bodies. Their fingers and toes are webbed, and they have gill slits in their necks. Their skin is light green and covered with patches of dark green, aqua, or blue hair. Male koalinths also share the aggressive behavior and loud bellow of elephant seals (although female koalinths are by no means passive).

Koalinth, like surface-dwelling hobgoblins, live in a rigidly organized, militaristic society. Their tribes are fiercely territorial and war with each other and with other aquatic races when their territory is compromized. They make their homes in caverns in shallow waters, ranging from subarctic to tropical seas. Like surface hobgoblins, koalinth supplement their own numbers with trained mounts, beasts of burden and war-trained bestial allies such as orcas, whales, sharks, and giant turtles.

Even moreso than hobgoblins, koalinth have a strong mercenary streak. Merfolk and locathah have both been known to hire koalinth mercenaries to help them fight against sahuagin and other threats. Koalinth are not as hateful toward aquatic elves as hobgoblins are to high elves; as far as the koalinth are concerned, the elves are just another race to fight for or against.

The discipline of military life is a part of koalinth upbringing and is integral to their identities. Even those who have renounced the evil of their culture still think of life in military terms: conversations are attacks and counter-attacks, journeys are hauls, and surprises are ambushes.

Koalinth believe that they were created from surface hobgoblins by Maglubiyet, who sought to conquer the ocean depths. However, the newly-created koalinth were approached by Panzuriel, the Lord of Krakens, who proved himself the true master of the deep and the koalinth remain his loyal servants to this day. Koalinth frequently work with other worshipers of Panzuriel, such as merrows, scrags, kapoacinths (marine gargoyles), and rogue sahuagin, and view the great krakens as sacred. However, most koalinth are uneasy around fire, the element of Maglubiyet Fire-Eyes.

We’re always looking for playtesters for our races, classes, archetypes and other designs here at Tribality. Wizards had the benefit of 175,000 playtesters over 2 years to get their ideas to the table; clearly we don’t have that luxury. Each of our builds are as balanced as we can design with a small playtest group and over a century of gaming XP. We are always excited to hear when players get these ideas on the table and provide us with constructive ways to make them better.
