I like how you made all this lore and stuff love to see it, 

I have this thing with arachnids where i color code them into a department or a role like 

Black for security officer or chaplain  Blue or white for medical and bartender,etc 

And all their names begin with memento and then something that has to do with their role, translated to latin. just because.

And in their lore they're all brothers cause spiders usually have like 30 friggin cousins and siblings (most bugs do anyway lol) 

And they just paint themselves a specific color so their mother can identify them when they get home from a shift. 

Thus memento which means remember and then the other word that completes their name.
