Tips:

a) pick a name, any name

b) let’s go with Kevin

c) fuck up a letter, preferably a vowel

- kevan

- kyvin

- kovon

- kevell

- kivoth

d) congratz u have a name

e) he might be called Tim but that might be short for something

- Timmos

- Timotheus

- Timiron (yeah just add “Ron” when in doubt)

- Tiroth

- Timarimos

Congratulations your Tim both has a cute nickname and a full name that sounds vaguely badass, or if not badass long-winded and unnecessary enough to be a Fantasy Name™.

Also try to make the syllables sound like their personality. A suave and socially smooth character could maybe not have any hard ‘r’ or ‘br’ or ‘tr’ in their names. Etc.
