Tyrenn

The Tyrenn ( http://www.reddit.com/r/Terova/comments/1o4ror/races_creatures/) Inhabiting the outskirts of the undead-filled Charnel Bogs, and terrorizing the southern brink of the Shattered Lands, these bipedal saurians often present complications to adventurers. A single thrust with it's bull-like horns can shatter rocks, not to mention the menacing set of fangs they sport.

Despite their size they eat mostly rodents, grubs and small fish but will go for larger prey if hungry enough. They are surprisingly competent swimmers and can hold their breath for nearly 10 minutes. At full speed, they can outrun a horse. Being cold-blooded they stay in mostly warm areas but will venture into temperate or barren zones in search of food.

They are difficult to tame but once domesticated they are staunchly loyal. If their tamer dies, they will grieve deeply and often wander off forlornly to die.

Two variants exist: the larger Whitescales, livng in the murky Charnel bogs, the smaller, yet more nimble Ebonhorns, hunting in the Shattered lands.

Whitescales can grow up to 3 meters (approx. 10 feet) tall, and can reach 6.5 meters in length (approx. 22 feet). These pale skinned beasts are both highly territorial and aggressive. It's incredible digestive system has allows it to consume the undead of the bogs, giving it a steady source of food.

The Ebonhorns on the other hand are "only" about 1.8 meters (6 feet) tall, and are a tad bit more tranquil. Nonetheless, they contribute to the many factors, which make traversing the shattered lands such a difficult feat. Also, unlike Whitescales, the Ebonhorns hunt often in packs of four, and are more tolerant regarding their own kin. It's natural predator is the Roc bird, which consumes these beasts frequently, with much pleasure.

Though the water in the Charnel Bogs is basically unholy water and will damage any living creature without some kind of resistance to negative energy. Perhaps the Whitescales or a common ancestor lived elsewhere and after feeding on undead for a time, became dependent on it for a food source. They migrated to the bogs following the undead that are drawn there, and something about the way Whitescales digest zombies gives them resistance (not immunity) to negative energy. It could be this resistance that resistance makes them a predator even to some of the stronger undead types.

Fun Fact: a group of Tyrenn is called a Lounge when stationary and a Mob when in motion.
