Euphemios, in reality, was a machine built by a highly advanced society under threat of extradimensional extinction. Too enlightened to build machines just for war, they were raised as equal living beings, given emotional motivation to protect their world as soldiers; they are not weapons, so weapons are not built into them.

Euphemios is the last surviving member of his race, and even in the dream world, he bears the weight of that world on his shoulders. Despite this, he is a friendly, emotional, passionate, and artistic soul. Why, there's not really any difference between him and a normal person's...

He is Atlas of the Fortitude, carrying the weight of his entire civilization in his memory. He won't let their ruin be in vain, and he misses the human family who raised him dearly.
