Alien Ruins in Newcastle sometimes, very rarely, drops a special nom artifact. It is random in drop and the ratio was something like 1/300 or something like that. It drops various stuff like Nom cannons or nom bs turrets etc, that kinda stuff. Sometimes RP value stuff (you may have seen some rp topics over the forums with special items, that kinda thing)
Where you have to shoot, I cannot remember exactly but if I remember right, it was one of the wing like side structures, not the main one.
We as Order tried it once and there was a drop, it is still in our Order|Armory actually.
