Seer: Someone who understands how their aspect works and learns things through their aspect. They are their party's strategists, having instinctual knowledge of their alternate timeline selves which they use to keep their party from making mistakes. They also have the talent of being able to hear their exiles more clearly than most. 

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.

Instead of seeing what will happen, they have the ability to see what could happen. They would either be an optimist or someone who's just cocky and overconfident, or just a stubborn individual who's determined to always see silver linings and solutions to problems even when they seem impossible.

Even if they don't actually believe in any religion, it'd be fitting if they used prayer to hone their power; just simply clasping their hands and closing their eyes, maybe even kneeling while they try and focus on the actual path that their team could take to get to the ending that they want. All seers are strategists, they just go about it in different ways and some have limitations on what they can strategize for.

An extremely powerful Seer of Hope would be able to see ways to reach goals that shouldn't be technically possible, or only just barely. If they can see a path forward that would be an incredibly risky thing to do with a low chance of success, it absolutely would succeed, but they would have to train themselves not to doubt the plan at all, and believe in it with their entire soul.

This is a simple classpect to describe, but a priceless member to have in your Sburb session.
