I was running around Fel a bit and went to Brit. I noticed a LARGE amount of NPC Faction Vendors and Guards at the entrance to TB Base. I came back on my Stealth Assassin and systematically killed each and every guard, kind of a pain in the ass considering 8+ guards were stacked on top of each other and caged in a ring of vendors. But i eventually killed them all, had to push past all 4 rows of vendors to get into TB Base. I then began stealing each and every Sigil and placing them in SL Base. Here's a few screenshots i took of it. Here's a few of me messing around.
