Heir: Someone who inherits their aspect by being given it, and/or representing/becoming their aspect, physically or metaphorically. They start out with their aspect affecting and controlling them on its own will, being saved or helped by their aspect when they’re in trouble, and eventually learn to consciously use it as they “inherit” it. 

Hope: This one is self explanatory. But also tied to belief in general. If you believe in something hard enough it might happen. They would be magicians in an rpg, as they have an immense amount of magical power. Holiness and angels are also representative of this aspect.

This is a classpect that is uh. Super fucking powerful. Neat!

So an Heir of Hope at their full potential would almost end up as a religious figure, but lets not get ahead of ourselves. Heirs start out being affected by their aspect without their input, so how would that work for hope?

I personally believe that this would come about in the form of really lucky coincidences happening for them. Basically, any time the Heir is in or trying to protect others from extreme danger, whatever big thing they're hoping will happen will happen, and they'll be able to save themselves or others in what looks like a legit miracle. Not one of those fake fucking miracles Gamzee talks about.

The baby miracles that they perform in the beginning of their journey are ones they don't have control over, and may work as a very mild and forgiving monkeys paw situation. For example, if they're thrown by a large imp and are desperate for something to lessen their impact or break their fall, they could just end up in a huge pile of mud or something else that's gross but still protects them.

As the Heir of Hope goes on, they become a source of inspiration to their planets consorts, their teammates, and the Prospitian army during the final battle. They learn how to inspire others, and inspire others without even trying. What makes this almost a broken class is that they function as a less powerful Muse but without the dying. They accomplish things and important tasks in the game on their journey that should be impossible. They very consistently perform miracles, on accident at first, and eventually on purpose. Hope wells within them so much that they can accomplish anything they want, and anyone on their side gains hope by proxy. Hence why I mentioned them being similar to a religious figure. The religious undertones of the hope aspect come from the fact that more than anything, Hope is belief that something is possible no matter what.

If me mentioning that a hope class is broken feels familiar, that's cause many of them are. It's canonically stated to be one of the most powerful aspects. Hope players are a cheat code for making something happen in the story that by all means shouldn't be possible. They're really cool.
