Arda-Mulissu (pronounced AR-dah moo-LEE-soo) is a 90ft tall good colossus. It is assumed to be the creation of Esarhaddon, like the many other constructs the mage employs. While it takes a humanoid form to travel, Arda-Mulissu is more commonly seen in the shape of a gilded palace in which Esarhaddon resides. Many have reported that spells and magical abilities cease to work around Arda-Mulissu. Though intelligent and capable of speech, Arda-Mulissu only converses with Esarhaddon.
Arda-Mulissu is both the name of a colossus construct and the region in which it dwells. To reduce confusion in cases where the intended subject is ambiguous, the construct is sometimes referred to as Shar-Arda-Mulissu.
