Some Alterhuman Symbols

Yes, of course!

The first one, the introject symbol, is a blend of the Psyche symbol, with the Elven Star spikes on the edges. It could just be personally how wei feel, but wei have trouble telling the difference between if we're an introject or kin, and for meus, myour status of being an Introject is very aligned with having a Kintype.

The Othershard symbol, wei're not entirely sure about this one, is a triangle that's now in two pieces, referring to being a piece of/shard of something. The circle around it is about the lifetime of what you're a shard of, with the circle referring to you, a point in the lifetime.

Shardmate is just a blend of those two, you're a shard of something + in a system!

Heathcliff explained the Factualkin symbol;
"an inverted Fictionkin symbol without the F, inside the head of a speaking bust. The head was to signify that it’s a humanoid type, the talking signifies that you could theoretically speak to your kintype in the shared reality, and the inverted Fictionkin is to show that they’re really kind of two sides of the same coin."

And Exme is an M inside of two broken apart X's! The thing you aren't anymore surrounding you (the M), but not actually touching or being a part of you.
