An animated classic work of art hell-bent on killing any human it lays its eyes on.

Usually humanoid/animal but can be more abstract.

Real teal, bronze

Very, but are patient about the kill.

Slow tracking. Can silently communicate with others to coordinate attacks. Since most are hollow, they are vibration amplifiers. The solid last longer and are mostly the ones to land killing blows. Smaller ones are scouts, but should still be feared.

Doesn't sleep or eat. Really good at staying still and waiting. Hide and seek. Finely tuned to vibrations.

Made of metal. Metal fatigue. Rust. The weather. Fire, if made of wood. Loud.

If a bell could scream.

Necromancers are particularly interested in these creatures, since partially destroying one nets the thaumers the raw material to great a gargoyle. It is a high risk gamble to obtain easier method to create a strong army/defense. This doesn't the small chance of rebellion.

Cities. Art galleries. Town squares.

Life finding a way.
