A green triangular symbol is found on both thorn and bad juju. Both of these are hive related weapons and have the same green “smoke” effect on them this effect can also be found on the necrotic grip warlock exotic, but the necrotic grip does not have the symbol on it. Maybe this little triangular symbol will represent the new subclass we might be getting in Witch Queen. It’s worth noting that the people who made bad juju and thorn had no affiliation with any larger group and weren’t familiar at all. The people who made these weapons were highly interested in the hive and so the symbol is likely of hive origin.
