Golem

"To whoever keeps taking my golems, stop summoning them! I need them as servants!" -Sign found after some Lidereith summoned a golem.

Golems are a creation by other species. They can come in two flavors, large 'male' versions and smaller 'female' versions.

Description
Golems come in any wide variety of shapes, colors and power levels. There are only two distinctions, the male and female, and that is only a measure of size. There are also giant golems, but they have not been seen for eons, and may no longer exist. Male golems are large, anywhere from several stories to ten feet tall. Females are more humanoid, much less lumbering as well. They will do whatever you want provided they can do the thing in question. If they cannot do what is required of them, they may do something random, or just kill their summoner/maker.

Creation
They are made by either summoning them from their 'home' dimension or the little known Contract Limiter Release, The Golem Summoner this summons a golem according to specifics. The second is to make one yourself. This is extremely difficult, and impossible to even the best Android makers. However, there are reports that mad scientists often are killed by their golem creations, however, this is unconfirmed.
