Nightfang

Nightfang was the last item to absorb Rundis and it absorbed all the malice and greed, but also his sentience.

A dark cold metal, nightfang is a cursed cruel curved blade with an eye in the pommel, Nightfang is a dark weapon, often binding itself to dark people.

Nightfang refers to itself in third person and has a Liverpool accent (or my attempt at one).

Nightfang is a sentient weapon, usually silent but talks when called upon, is only heard by it's wielder. Nightfang cannot hear but can see its surroundings within 60', and can read lips, it can also read the mind, and sense emotions of it's wielder.

Nightfang likes to cause it's wielder to kill its sleeping companions.

its handle ,pommelt and handguard are red, and the wraps are also red, the iris of the eye is black.

Nightfang is always spotless, dirt seems to avoid it, it despises dirt, and sucks in blood.

Nightfang requires attunement

Nightfang absorbs the blood of it's victims, for each victim slain with a final blow coming from Nightfang, nightfang gains 1 charge.
