Those markers would be mine - the Deft Punks! They started out in the Manky Stink Sewerage Works, but stole a Workshop from the Undersiders after their failed night-time ambush!I really like the bunched up ones. It's exciting to find out what they are and how it might affect the ongoing fluff. Who had the and the dark blue? That looks like a blossoming epic rivalry.
Something i forgot to post earlier, the fate of @CaptainDangerous till the next meet.
And my markers are the Black V's on the yellow background at the top.
