It seems odd that Guild Wars 2, a video game, would have a philosophy embedded in its story, but Guild Wars 2 is an unsual game. It has an open world format that encourages people to help each other in the playstyle.
The world lore has a character that did not agree with the group that he came from. Ventari had a very different view of the world.
He wanted to live in peace with others that were different from himself. Ventari was a Centaur who did not hate humans or any other of the other races in Tyria. He had a set of principles that he lived by. Ultimately, the Sylvari (a plant race in the world) adopted them.
I like the principles because they align with the principle of Love. And Love is who I think God (Father, Son and Holy Spirit or however God has revealed themselves to you) are. They do not force anybody to believe in them. And they love us all.
