Oh whoops, this one got kinda buried. My inbox is a mess at the moment.
Anyway, standard Heart-based warnings apply. This Aspect is based on what you consider part of your identity and thus could be anything and everything. I can only provide even looser guidelines than normal.
Interests/Traits
Anything is fair game. But as a Heart player, whatever they’re into they are very into. Since they are a Seer, they might be a little more structured, analytic, or information/text-based about their hobbies. For example, if they like sports, perhaps they have a fondness for memorizing world records or batting averages. If they’re into a show, they write a lot of fanfiction about it and know weird stories about the cast and crew. If they have a cat, they can tell you everything about the breed.
A Seer of Heart might be very into reading self-help and self-improvement manuals. Maybe they then attempt to make other people follow those tips as well. They probably dissect their friends’ actions and have an uncanny knack for knowing when they’re upset or otherwise ‘not themselves’. They have made people watching an Olympic sport. Good luck lying to them. They can tell if you’re lying to yourself.
Game Powers
This will be filtered through their interests, as I said before. Some generic Seer of Heart powers might include being able to gain information about npcs, agents, or enemies just by looking at them. Take a glance at that monster and you know what it is, what its stats are, and the best way to kill it. Eyeball that agent and you know exactly how to recruit them to your side. If any player or enemy is using disguises or illusions, the Seer will see right through them. They can’t be fooled, because they’ll always see who someone truly is. If any of their teammates are being possessed, controlled, influenced, etc., the Seer will know right away and may be able to take action.
Roles are bound up in the Self, so a Seer of Heart might be able to help their teammates understand what they’re capable of and how to unlock their powers. They can figure out what roadblocks the person is hitting as they try to develop and come up with ways around them.
With Heart as soul, maybe the Seer of Heart can see ghosts! In a session without dreambubbles, this could be handy, especially if they hang out with their Time player to gather more information from doomed timelines. Even with dreambubbles, guardians and npcs usually don’t show up… the Seer might be able to chat with them. Or maybe they can just tell what areas of the game have seen a lot of death, allowing them to dodge traps or reconstruct past events.
Arc/Development
The path of a Heart player seems to involve coming to terms with their Self. Seers often panic when they lose control and ‘blind’ themselves in some way to compensate or pay penance. Maybe the Seer screwed something up because of a personality trait or interest they’re ashamed of, and they try to make themselves something they’re not. Or maybe they hate being able to see their friends so clearly (it’s not always pretty) so they try to convince themselves that they’re wrong, and then their friends’ bad traits get them hurt. Eventually, a Seer of Heart would need to accept that all of our souls contain good and bad. By understanding both, the Seer can appreciate people for who they are and help guide them into being the best they can be.
