The bear

The thing Caruso keeps in his ceiling. It beats Fenris, and nothing in the saga ever says what it is.

What it is like

Eight feet upright, eight hundred pounds, brown fur "the color of dark earth", claws "like obsidian daggers" and talons ten inches long. Its breath reeks "of decay and old blood". It drops out of a collapsing ceiling that came down on cue, "precisely placed, carefully timed".

It takes Fenris by the throat from behind and lifts him off the floor, and his own strength does nothing against it.

Why Fenris thinks it is wrong

Not the size. The obedience. He works it out while blacking out, and it is the only analysis the saga offers:

Bears were solitary creatures by nature, proud and fierce, apex predators that bowed to nothing and no one. This level of compliance, this willingness to serve as someone else's weapon - it wasn't natural.

And the detail he cannot place:

there was something else in the rhythm [...] the mechanical precision of its movements, that felt fundamentally wrong. Familiar in some distant way, but corrupted, twisted into something that violated the natural order.

Then he is unconscious and the thought is never finished.

It has been bitten

Ch. 86 is the detail that makes it a mystery rather than a monster. Fenris wakes alone with it and sees its wounds before it sees him:

deep puncture wounds that wept dark blood. Some were fresh, still bleeding freely, while others showed signs of infection.

Bite marks, on its muzzle and neck, in layers of different ages. Something had been biting this animal repeatedly over a long period, and it was not Fenris, who had been unconscious.

Its behaviour has changed too, from the controlled thing of ch. 84 to "less controlled than before, more agitated", pacing "like a caged animal".

It also bit Fenris while he was unconscious and did not kill him. The wounds were "precise, calculated - designed to weaken rather than destroy", which is not what a maddened animal does.

How it dies

Fenris tears its throat out. It rears up, exposes its neck, and he goes for the artery and holds on through ten-inch claws opening his back.

The chapter ends on him refusing to think about what he has just done, and the comparison it declines to make out loud is Milo, killed the same way, by the same jaws. See fenris.md.

Open questions

• What it was. The saga raises the question through its protagonist and never returns to it. Caruso treats it as equipment and dies three chapters later without explaining it.
• What was biting it, over what looks like weeks.
• What "familiar" means. Fenris has met something like this before and does not place it before he passes out.
• Whether it was made. "Corrupted, twisted" is the narration's phrasing and not a character's claim, which is as close as the text comes to saying so.
