Dead semi humanoid species

Underneath the ruins of Netlor and the famous statue are catacombs with the remains of a semi humanoid species

Larthop the First Son of Darkness enters these Catacombs in  Eric Olafson, Midshipman. "INTERLUDE: FIRST SON OF DARKNESS " (part of chapter 5). It is the year 5018 OTT

Here is the scene:

>>>Larthop had reached the bottom of the stairs and followed the narrow corridor chiseled out of the rock. The corridor was part of a burial site. Catacombs left by the same civilization that built the city now in ruins around the statue. Not many knew of these catacombs and he knew Union Xeno Archaeologists would give their eyeteeth to examine this place. There were alcoves in the walls and in it the dry rotten bundles and shapes of a dead semi humanoid species. This was unimportant to him and he had no intention to speak to the dead. <<<

Later Xeno Archaeological research (around 5053 OTT ) gives the remains a name : "Old Netlors "
