The Komahd found the Mn'n (as the name should be) a willing, eager client race. Keen on acheiving status, the Mn'n asked the Komahd perform gene-engineering as radical as possible without provoking the wrath of the Institute of Uplift. They rapidly passed all tests - only to face refusal from the Tumahd.
The Mn'n are oviparous parasites. They coexist with a pint-sized animal, the sulm. A female Mn'n place one egg in a cocooned sulm. In prehistory this may have been predatory, but today a symbiosis exists. The Mn'n parent provides nutrients, enabling both the sulm and the hatchling Mn'n to survive.
