Per 
Get. Keep. Shelter.
The 'Get. Keep. Shelter. Organization' is a group consisting of an estimated 15-20 individuals.
There are five (5) heads or leaders of the Organization who seem to operate over the rest of the lower-tier members (Three men, two women). The highest tier, calling themselves 'The Five Heads', appear to have traveled from around the 1920s (based on apparel and manner of speech).
These five seem to be under the direction of another entity whom the identity of which is currently unknown. The Five Heads have only ever referred to the said entity in emails and phone calls as 'Boss'.
The Boss has only ever been heard over one phone call with one of The Five Heads. The entity's voice has often been described as deep and gravelly.
The following message is the only ever recorded call in which the Boss is heard and lasts just under seven seconds:
One of the Five Heads: The fuzz is closin' in, Boss.
*a brief period of silence*
Boss: Not to worry, it will begin soon.
One of the Five Heads: All right. We'll get everything ready.
Note: At this time is remains unclear as to what event they are referring to, or whether it happened in the past, or the present.
There are multiple calls, texts, and emails that have been recovered in which members and the heads of the GKS Organization appear to be conversing. Many of these have been discussing the major lack of resources that the organization possesses. In all cases of the conversation between a member and one of the heads, the head has always reassured the other member that the Boss has everything planned out.
The method as to how the Boss supplies the Organization with man-power, funding, weaponry, and lodging/operation housing is unclear.
