Topic: Boba Fett armour symbol

I was wondering about the meaning of the symbol Boba has on the front of his armour:

I think I heard once that it's Concord Down symbol but I can't find the source.
Do you know anything about it?

Hey Mahiyana! I actually made that particular graphic.

The backstory for it, which is screen inaccurate by the way, can be found here:

This is the subpage I took it from ^^
So you made it? Great job then ;)

But still, there's nothing about the meaning of the symbol there...
(or at least I can't find it... that layout tends to be confusing...)

It's the clan sign of Jaster Mereel, Jango Fett's adopted father.

Where do you know this from? :)
Any specyfic book or comics?

I can't remember specifically. I know I did a lot of research on it at some point bc I was very curious but i think it was a book. Sorry. If I remember, I will be sure to tell you though.

Thank you for your answer :)
If I find proper sources maybe I'll research it myself ^^
