This creature is named Truth. It is a sapient postcreated and doesn't believe in gendered pronouns on itself.

Truth is not the first one, but is one of the oldest postcreated creatures. It is mostly made of iron and all “fur” and “feather” -parts are carbon fiber. It has always had calm demeanor and had felt like “old soul” even when it was younger. It has lot of compassion for regular creatures, people and animals alike, and still seeks out those who are reaching their last moments, and comforts them.
However, it has kept professional distance to too person-like feelings, and many individual fates it has seen - no matter how cruel or sad - don’t get on its mind. It is patient and never gets angry to anyone and overall its reactions to everything are very mild yet it has generally positive attitude. With all of this, it sometimes really surprises those who engage conversation with it, by telling a punny joke out of nowhere. (“I do have a mind of steel indeed - my head is literally iron.”)
It possess unique power different from what even the sins have in their skillsets.

tl;dr: Very respectable and serious creature who occasionally would tell the worst dad jokes.
It has iron content so big that you could slap fridge magnets on it, and it would just look at you with calm amusement.
