Description

MI666 - The Service's line of work requires a large number of highly specialized professionals. This is usually related to anomalies that require much effort and an unorthodox approach to containment. To address this, MI666 is formed. Expedition groups are teams of varying sizes that specialize in specific roles or respond to specific situations. Every group has a name consisting of a relation to Britain and a number; clarification prefixes and/or call signs may be employed in some cases. MI666 acts as the international barrier between the anomalous world and the United Kingdom.
