Bitanling was as old as the coming of the Dark Ones, but was finally slain in 27 A.S.. Despite its status, it appears to have been a simple turtle, albeit one grown to immense size. 

A point of debate is that Bitanling was described as growing tired in the moments leading up to its demise. Indeed, Master Ophelia had factored this into her plan to slay the Beast. Quite a few Hunters maintain that Beasts tire from regenerating their bodies. A few even wonder if Beasts might not be as different from animals as we believe, since they have been observed to eat and sleep.

Many Hunters disagree with these observations, though, while others do agree but add that only weak Beasts tire and refuse to believe that Bitanling could be considered as such. Experiments to settle the matter have been suggested, but none so far have been permitted.

The Clamber Fiends assaulted Nescetan in 37 A.S.. They were reportedly similar to a pack of wolves, albeit with the ability to run up and across walls, and struck in large numbers. Their attack was vicious, the Beasts actively following people as they fled or hid. This viciousness could be used against them, however, as the Hunters managed to lure them into a trap simply by making enough noise.

The sheer number of Clamber Fiends does raise an interesting point on the creation of Beasts, though. Namely the question if large numbers of similar Beasts occur when large numbers of similar animals happen to die in the same place, or whether the Dark Ones are actively creating specific minions, perhaps by steering their existing Beasts to kill certain animals in order to fulfil their desires.

It should be mentioned that the Darkhearts of Iosabale, discovered in 43 A.S., were actually discovered nowhere near the Waynairdian town of Iosabale. Rather, they were discovered by Hunters on their way home to Fenblith from that town, but the name seems to have stuck.

The implications of these Beasts are dire. They were discovered in a cavern filled with marks similar to those described near Melsciff in 8 A.S.: long and narrow with sudden angles, apparently distorting sight and causing a feeling of loneliness. Moreover, the Beasts themselves were elongated – their bodies, limbs, and nails stretched out – not unlike Melsciff’s Twins was.

All this combines into the suggestion that some Darkhearts may have found a way to entice the Dark Ones into transforming them into Beasts. The state of mind that might lead to this goal beggars belief, but it is a possibility filled with threatening potential.

Found by a Novice in 32 A.S., the Drowned Woman hid in the sands of Silwan’s beach. It was reportedly quite weak, unable to do much damage and requiring a substantial amount of time to regenerate from a regular injury.

However, one aspect of this Beast stands out: the human parts of the Drowned Woman were apparently bloated. Notably, it takes at least three days for a human to begin to bloat underwater, at which point the internal organs have been decomposing for two days minimum.

This underlines the belief that not only fresh bodies are at risk of transformation, but all corpses are. And yet, almost all Beasts appear to arise largely intact, the people and animals they sprang from evidently dead for hours, not days. The cause of this discrepancy remains to be seen.

In 22 A.S., an errant Hunter encountered the King of the Forest outside Gettildow. It reportedly ignored multiple musket shots, only going down after sustained fire from a prototype repeater. More controversially, it was suggested to have had a spark of human intellect.

The latter is largely based on a single report suggesting the King of the Forest might have been trying to speak. Many have been inclined to reject this notion, but examination of the Beast’s head did suggest it may have once been a human’s, at least partially.

This has led to the uncomfortable question if Beasts – particularly those made from human remains – retain some of their mortal minds. Unfortunately, there is currently no way to definitively research this, and so the matter remains an open controversy.

Appearing in one of Gladill’s mines in 17 A.S., the Knockers posed a particularly large threat. Immensely strong diggers, they would trap their victims by causing cave-ins before emerging to claw and bite them to death.

The Hunters managed to bring back some of the nasal appendages for study. Close inspection revealed that they were covered in what appeared to be taste-buds, meaning they probably found their prey by tasting the air, since they lacked eyes.

Notably, there is a species of mole that features a similar adaptation, but as it does not occur in Iseron the question arises whether the Dark Ones may have recreated that ability here. The implications of this are tough to parse, and the fact that other Hunters have since encountered similar Beasts adds to the mystery.

The Muck Toads, which appeared near Ditmus in 12 A.S., present an interesting question. Superficially, they seemed to fall into that category of Beast characterised by dead animals becoming substantially larger during their resurrection. However, the Hunters discovered – in quite tragic fashion – that the Muck Toads possessed a potent venom, which they could apply with their sharpened tongues. This venom caused instant pain, soon followed by convulsions, and was apparently quite deadly.

Notably, Hale Bark ointment seems to have had little effect against the venom. As the ointment is a beloved general antivenom across the global network, this suggests some level of alteration of the Beasts’ venom by the Dark Ones. Unfortunately, no Muck Toads survived the Hunters' vengeance in good enough condition to allow any physical study.
