Dungeons & Dragons
The Philistine Amalgamation is a term given to categorize the loose affiliation of orcs, goblins, and assorted low-giants. These species have been observed collecting into armies and villages, which led human needs to label and identify the group so they could track its growth and development.
The term is used exclusively by humans and is not representative of a larger government or nation system. These races largely coexist because of cultural hegemony and the need for survival against human populations.
