This agent has found out that there are camps located at the pyramid site.  Each camp is a lizardmen camp with some kind reptillian commanders.  There is a map provided on this page showing distance and size, it includes estimates that the agent provided.  The red circles represent a 1000man/lizardkind garrison.  They have large tents20-30, small tents (100 or so) , some mobile wagons, war machines and small wooden cages with humans held within.  The humans inside are kept covered.  They are obviously held captive.  There are small cages in each encampment.  The cages are kept covered most of the day.  At night they seem to move the prisoners from encampment to encampment.  Sometimes in wagons, other times all tied together.  The lizardmen have taken a few from each cage each night before moving them, they kill one and hook him/her to their spit. More detail can be found on the internals of the pyramid design chart the Agent #01 found during his investigation.
