Argos

Argos were amoeba-like creatures covered in eyes and mouths. They were found in wildspace, around the same areas where beholder nations laid.

Society
On Toril, argos could be found in the Moonlit Tower and the lowest levels of Undermountain.

Notable Argos
An adventuring party carrying the Stone that Speaks was slain by an argos on the site of Tempus's Tears.

An argos was brought to Spindleskull's Tomb by the Zhentarim wizard Baergil. The creature was kept there for the purpose of killing any fellow Zhent wizards transported to the tomb by its captor, using a specialized variant of a teleport spell.
