Four Templet Avatars

Although making a tabletop Rpg was what made me think about this, it may end up being more than this.
Goal: Making a tabletop Rpg about making your own universe
1. Cards and cartomancy: cards dealt like a card game until the pack is dealt to all players. Or each player has their own pack. Spades= events/history, Clubs= place/work/social stuff, hearts= love/comfort/healing/pleasure, diamonds= cash/treasure/hardiness
2. Players play cards to build a basic spread of at least one person, one place or places, a historical event, and some object or objects, but these four cards are played face down and flipped over only when another player visits, the player that plays these will then explain what each card represents
3. Players play off of each other by visiting another players universe, and each visiting player chooses one of the cards to partake in the first round
4. The hosting player or players plays his or her cards to keep them there or to expel them after the first round
5. Hosting players can use their cards to define rules or build on basic rules and the visiting players have to abide by them
6. Cards are played creatively as some person, object, place, history/event, etc. but the card can’t represent something that doesn’t relate to it in some way (six loves attached to a six of diamonds, or six diamonds for six loves when they should be six treasures)
7. Hosting players have the option to host or expel visiting players each round, expelled players cannot visit a universe expelled from unless the host player removes the expelling cards, hosting requires making things happen each round for each of the visiting players, and a visiting player has to sacrifice a card to leave or if the hosting player does not play a card for a player during a round, that player can leave freely without sacrificing a card

Now, if I take this principal and apply it to writing a certain story concept… umm…Book of Particles…, I could adapt it to mean Four Templet Avatars and three of them visit the other one and it rotates around until they visit each of their universes for a story. The four of them know each other enough to be friends. The concept means they’re not mortals anymore.
I thought, have Weston Quinn, Reogold, Snekkey, and Amoebus be those four Templet Avatars. Yet, no, they all have stories that could be written and or unique enough. Weston Quinn could be interesting.
So, perhaps four regulars from earth or four other characters.
