Arglath

Arglath was a massive Beholder elder orb of Ooltul presumed alive in 1370 DR.

History
Arglath in the past was a Ooltul beholder of monstrous size; one time it tried to conquer the Twisted Tower of Ashaba in Shadowdale but was destroyed by Elminster Aumar. After from time to time Elminster acted as "Arglath", favored by the situation that nobody know the death of the elder orb; in that role Elminster foiled Manshoon's plot of domination over Zhentil Keep and received in exchange a list of True names of powerful beings, including the Phaerimm Triumvirate ruling Ootlul.
