Of the four major xenoarchaeological sites associated with the Morrigi, the most dramatic is the famous Wyrm of Daam'to. Discovered in the dry salt wastes of the continent of Lokris, the Daam'to salt mine had preserved the physical remains of fourteen Tarka and one Morrigi female in a state of natural mummification for many thousands of years. It was excavated in the Tarkasian year 9087, and the associated artifacts have been on display in the Imperial Museum of Lokris for several centuries.

Piecing together the ancient site report with the items still held in curation at the Lokrisian capital city of Ku'Galu, it would appear that the individuals found in Daam'to were all killed when a section of the salt mine collapsed, burying all fifteen individuals under many tons of salt and rock. The Morrigi, judging by its skeleton and equipment, would have been a well–developed adult female — parts of her skull, left wing, dorsal and pectoral spines were recovered, as well as three thick longbones and there are many fragments of metal which were likely part of some sort of protective armor. The Tarka group consisted of six females, seven adolescent males and one Changed male, the latter of which was armed with an impressive bronze spear and a warhammer of the Ku Dynasty. The remains of three of the females and four of the adolescent males are heavily scorched, as if they had been subjected to partial immolation.

Taken in context with other archaeological finds and current knowledge of Morrigi territorial wanderings, the Wyrm of Daam'to raises a number of disturbing questions. It is an indisputable fact that there is no creature in the fossil record of Old Earth, Ko'Kuma, Tcho'to–pre or Muur which possesses the mosaic of traits common to Morrigi males and females. Nonetheless, creatures with a striking resemblance to Morrigi seem to have cropped up repeatedly in the legends, art and iconography of all four species. All four species have at least one word, ( and sometimes words in several languages ) for dragon — these words almost immediately spring to mind upon seeing a live Morrigi for the first time.

Some dragons in the legends of all four species were interested in collecting treasure and are often depicted enthroned upon massive beds of precious metals, art or gems. In other cases, divine winged visitors appear to have exercised profound influence over political and religious leaders and even to have established some sort of domination over a historical population, as in the Feathered Serpent legends of Old Earth and Tcho'to–pre. It seems distinctly possible at this sitting that ancient Morrigi visitors may have established outposts, trade and possibly even imperial control over historical populations of Human, Hiver, Tarka or Liir. At present, however, the Wyrm of Daam'to is the only direct evidence for this hypothesis.
