Golem

Golems are magically animated constructs created by wizards and other masters of secret lore to guard important places of treasure. Golems possess just enough awareness to follow orders. Single-minded, they ignore all but the most obvious dangers. Created to guard their masters and their secrets, golems have no sense of self and follow order without question.

Lore
A golem is given "life" by an animating spark from the Elemental Chaos. This spark is not a soul or an independent creature, but raw vitality that gives the golem the power of movement and a glimmer of sentience.

A golem's creator has complete control over its actions. Without its creator present, a golem tries to obey its last orders to the best of its ability.

Golem types include iron, flesh, clay, stone, ice and others, mostly held back by the creator's power and imagination.

In the campaign
In the battle on the outskirts of Everrain forest, where Vincent Winterbourne, Lymond Vickary and Salvador Valeriano helped the Tethyrians against a Cowled Wizard and his Flaming Fist soldiers, they later discovered that the hardened military were in fact not men but constructs. The exterior was flesh but they discovered a mithril skeleton and parts below the surface. Apparently, they were a kind of sophisticated mithril golems, highly enhanced to command troops and operate on a battlefield.

The group, on that skirmish, only managed to destroy one of them.
