I've introduced my group to the "Irish Republican Army in Exile" (IRAiE, pronounced "Éire"). I've made no bones that this is a Terrorist organization (Although they do target only government and military sites of the Tir elves, both Tirs, BTW.) and try to limit the collateral damage as they're fighting a war for hearts and minds in the world as opposed to the idea of "Bullets, not Ballets". But they do have a major smuggling organization going on, particularly weapons, but they'll move anything into the Tirs that will hurt them in any way (Drugs, chips, hazardous waste, etc.). Not nice people at all, and I've made no bones about how they act.
They're direct contact is an Elf that found the people that were part of the bureaucracy that kicked his (Human) family out of Ireland and proved his loyalty to the cause with a bunch of pickle jars. I'll let you guess the contents of said jars. He's a Fixer that specializes in smuggling runs, but has a hobby with explosives that he loves. A lot. ("I got a bus.").
Not exactly sure why, but my group likes them.
