What do you think would be a good focus?
ARC Team refers to Wuhan-Baxter's Asset Recovery and Containment Team. It is explained in mission Zbarro#641 in the supplement The Vault and in the The Company RPG I think.
I think L.O.O.T. is homebrew. I did some searching on Discord, and I believe they are objects influenced by the energies of an Anomaly. Logically Out Of Touch objects.
