As a child, T was friendly towards many of the other letters. One day, F and L got into a fight, and T was used by F, along with A and R, to make the Word "fart". This embarrassed L, who along with O, made F along with R, I, C, and K spell the word "FRICK". Angered, T snuck under the ground and hit F in the back.
Over time, T also grew as an adult. One day, F decided to get revenge on all the letters. At some point, T was hammered into the ground by F.

Y was only seen for a short time as a lowercase letter in ‌nZ…. From o alerting everyone, after she, a and s saw the word "frick", she quickly closed her eyes in fear, and said her name, showing she may have Kakologophobia (the fear of bad words). (And F killed X)
In Y, after she saw X's dead body, she crouched, quickly looked at the sky, and said her name. After F was defeated, she and N were puzzled after seeing that F just wanted to form "FRIENDS".

Е got revenge for Р by pranking him, spelling the word "гудок" to embarrass him in front of all of the other letters.

Z is a planet in the shape of the letter Z and is the home to every other letter that existed. Z saw what happened to F, and cried after watching his descent into madness, showcasing their apparent compassion for the rest of the letters. Technically, it's gems (...) are its three moons, since it’s the planet.
