A group of 8 forces setup as part of an expeditionary force following the arrival of the Vishim on the continent of Halcron.
An expeditionary force shipped out to the waters in the direction of Dessai. They disappeared without a trace. All those who investigated went mad, babbling about monsters made of men, ships and fish. It is assumed that these 'monsters' disposed of the entire unit. When there was a subsequent investigation, however, there was nothing to be found.
The monster that is most speculated to have eaten the unit is the Fathom.
