Broodmother- Dragon Age Origins (Codex 7, Creatures)
It is well-known that darkspawn carry off those captured in their raids to underground lairs. Most assume that the prisoners are eaten, or somehow tainted and turned into darkspawn themselves, though this could never account for the sheer numbers of the horde. Forays made by Grey Wardens into the underground have uncovered the answer.
When exposed to the darkspawn taint, men are driven mad and eventually die. Women, however, undergo great pain and gross mutations that cause most of them to perish. Those that survive, however, become the grotesque broodmothers. These giant, twisted behemoths birth many darkspawn at a time; a single broodmother can create thousands of darkspawn over the course of her lifetime. Each type of darkspawn is born from a different broodmother: Humans produce hurlocks, dwarves produce genlocks, elves give birth to shrieks, and from Qunari are born the ogres.
Newly hatched dragons are roughly the size of a deer and voraciously hungry. They live for a short time in their mother's lair before venturing out on their own. The slender, wingless creatures are born in vast numbers, as only a few ever make it to adulthood.
Drakes
Male dragons never develop into the winged monsters of myth. At most, their forelegs grow the vestigial spurs where winged membrane might have been.
Once they have fully matured, males immediately seek out the lairs of adult females. When they find one, they move into her lair and spend the rest of their lives there, hunting for her and defending her young. They will aggressively defend her nest, and many would-be dragon hunters have been lost to their fiery breath and crushing blows from their tails.
Dragons
Female dragons take much longer to mature than their male counterparts. They too undergo a metamorphosis of sorts at adulthood: But while males lose the use of their forepaws, females actually grow a third set of limbs specifically to serve as wings.
Young females travel great distances looking for suitable a nesting site. Because of their nomadic habits, these are the dragons most frequently encountered by man.
High Dragon
A fully mature female dragon is the high dragon: the great monster of legend, the rarest of all dragonkind. These dragons hollow out massive lairs for themselves, for they need the space to house their harem of drakes as well as their eggs and the dragonlings
High dragons are seldom seen. They spend most of their time sleeping and mating, living off of the prey the drakes bring back. But once every hundred years or so, the high dragon prepares for clutching by emerging from her lair and taking wing. She will fly far and wide, eating hundreds of animals, most often livestock, over the course of a few weeks and leaving smoldering devastation in her wake. She then returns to her lair to lay her eggs and will not appear in the skies again for another century.
Mabari hounds are descended from pack hunters, and like their ancestors, they are highly influenced by a defined order of dominance. The primary method of determining that order is by claiming territory through scent-marking major landmarks. Once established, the dominant mabari gains a substantial increase in confidence and stature within his territory, a trait that indirectly benefits master as well as hound.
Arcane Horror- Dragon Age Origins (codex 2, Creatures)
"Upon ascending to the second floor of the tower, we were greeted by a gruesome sight: a ragged collection of bones wearing the robes of one of the senior enchanters. I had known her for years, watched her raise countless apprentices, and now she was a mere puppet for some demon." —Transcribed from a tale told by a templar in Antiva City, 7:13 Storm
Demons, of course, have no form in our world. When they enter, either where the Veil is particularly thin or through blood magic summoning, they must take possession of a body.
When a pride demon takes control of the corpse of a mage, an arcane horror is born. Although they appear to be little more than bones, these are fierce creatures, possessing not only all the spellcasting abilities of a living mage, but also the capacity to heal and even command other animated corpses.
Any creature infected with the darkspawn taint that does not have the good fortune to die outright becomes a ghoul: a twisted shadow of itself.
The name originally comes from men—whether human, dwarven, or elven—who became tainted, usually while being held as a captive food source by the darkspawn. They would turn cannibal, preying on other captives, slaves to the will of the archdemon, driven mad by pain.
During a Blight, the corruption of the darkspawn spreads through the wilder areas of Thedas and infects the animals found there. This produces grotesque, enraged bears called bereskarn as well as blight wolves.
Fortunately, ghouls rarely survive their corruption for long.
"It is rather unfair, the reputation that the wolf possesses in Ferelden. For a people that so clearly adore their hounds, Fereldans simultaneously harbor a distrust of wolves that borders on the unreasonable. Unreasonable, that is if one were not familiar with the ancient legends regarding werewolves. There was a time in Ferelden's past when demons inhabited the bodies of wolves in great numbers, causing the wars against werewolves and spreading great fear and panic. The werewolves were slain, but even today the noble wolf is still looked upon with distrust."
—From Legends of Ferelden, by Mother Ailis of Denerim, 9:10 Dragon.
An attack by wolves upon civilized folk happens rarely, often only in times of desperation and even then only when the wolves have the advantage of numbers. This can change during a Blight. When darkspawn rise onto the surface their presence dramatically alters the savage nature of normal beasts.
In Blights past, as the corruption of the darkspawn spread through the wilder areas of Thedas, it would infect the animals found there… and the more powerful of them would survive and be transformed into a more vicious and dangerous beast. A blight wolf is one such example, mad with the pain of its infection, and only through the overriding command of the darkspawn does it still retain some semblance of its pack instincts. Blight wolves are always found in large groups and will tend to overwhelm a single target if they can, using their numbers to their advantage. It is fortunate that these creatures rarely survive their corruption for very long.
Marbari War Hound- Dragon Age: Origins (Codex 17, Creatures)
Dogs are an essential part of Fereldan culture, and no dog is more prized than the Mabari. The breed is as old as myth, said to have been bred from wolves who serves Dane. Prized for their intelligence and loyalty, these dogs are more than mere weapons or status symbols: The hounds choose their masters, and pair with them for life. To be the master of a mabari anywhere in Fereldan is to be recognized instantly as a person of worth.
The mabari are an essential part of Fereldan military strategy. Trained hounds can easily pull knights from horseback or break lines of pikemen, and the sight and sound of a wave of war dogs, howling and snarling, has been known to cause panic among even the most hardened infantry soldiers.
