The first two look like greek letters, beta and phi in the first one and chi and ‘wiggly’ (that was what my professor called it cause he couldn’t pronounce it properly) upside-down in the second one, and the last two have the word ‘Allah’ in Arabic in them... I’m not seeing any connection between the first three at all, and the first and fourth only both have something that looks vaguely like phi in them.
BTW are you named for a character in "Watership Down"?
One of my favorite books!!!
Unfortunately, I always identified with "Fiver"...
