The Day After Ragnarok: One Snake Cult, One Ranger
The Office of Special Investigations
The Office of Special Investigations, or OSI, is a little known branch of the Texas Rangers under the command of Ranger Chaplain, Capt. P.B. Hill. The OSI investigates and responds to cases involving supernatural elements. Their mission is to protect the people of Texas, to identify and eliminate supernatural threats, and to identify, aid, and monitor supernatural forces that are benign or otherwise confirmed as non-threatening.
The OSI has a small research lab where they do some work with Ophitech and arcane artifacts, and maintains several secure vaults where supernatural items that are dangerous but which cannot be destroyed at present are stored. The OSI maintains a friendly working relationship with Howard Hughes, who has been known to lend prototype weapons and equipment to the OSI for field testing.
The OSI will occasionally issue advanced or arcane items for Rangers in the field.
