You humans know nothing.
You are the latest of many races to come to this world – brought here by the parasitic elves who were invaders from another realm. Brought here to fight their wars and serve their interests – you were to be their puppets. But you did pull a fast one – is that how you say it? “pull a fast one” to play a trick or confidence game? Beside the point – they are gone and good riddance to them. May they forever rot in what ever eternal damnation they richly deserve.
Our hatred of the elves is that of children long abused and abandoned by their parents. Only the priests of Nomog-Geaya and a few scholars know the truth of our origins. For reasons of their own, the elves mixed their blood with that of goblins. But they deemed the offspring – our ancestors – hideous and deformed. So they drove their creation to the wasted west beyond their verdant lands.
