An advanced form of homunculus, Magens are artificial humans engineered from exotic mixtures of alchemical fluids, which are poured into a specially crafted mold and then "set" into a solid form, akin to gelatin. The result is a greyish white-skinned humanoid with an  determined by the mold used - vain wizards have been known to sculpt magens that look like clones of themselves - with the warmth and textural consistency of human flesh. Artistically inclined magen masters can paint their magens to look less - or more - inhuman, and a skilled artisan can even add texture or the semblance of hair to the normally eerily smooth and bald creatures. Magens normally look like humans, but may be sculpted to have inhuman traits; this can lead to a magen looking like everything from an elf to a fiend to a monstergirl.  They never bleed or bruise, they lack any discernible anatomy, and, when slain, their bodies dissolve in a burst of acrid, multicolored smoke and flame.

It's generally accepted that magens were made by skilled wizards who weren't yet strong enough to make a fully-fledged golem... but this kind of flies in the face of some evidence; magens are actually much smarter than golems, even if they retain the golem's characteristic lack of free will, and are capable of speech, following detailed commands, understanding complex procedures to at least the same level as a human of average intelligence, and can even be taught to make simple decisions on their own. Also, making a magen is still quite a lengthy and expensive procedure, so they're not exactly winning points on the quick and cheap meter, either.

Officially, magens have no emotional capacity, although they can be taught to feign emotions to some degree. This justifies their willingness to undertake obviously suicidal orders if directed. And yet, should a magen's master die, they fly into what can only be described as a berserker fury, madly attacking anything and anyone until it is destroyed. Combined with their innate lack of free will - except in incredibly rare circumstances - magens are typically slaves for their wizard or artificer creators, though some lonely yet antisocial types have been known to treat their magens as their friends (or, perhaps, lovers).
