"Calsidiu"

Calsidiu was the claimed founder and leader of the Myreque resistance group. He is mentioned several times, most prominently by Veliaf Hurtz, throughout the first five Myreque quests. However, at the end of The Lord of Vampyrium, Veliaf admits to the player and Ivan Strom that Calsidiu was a completely made up fabrication created by Veliaf and Safalaan.

The pair had come up with a supposed and unseen 'leader' in order to give hope to the Myreque that there were many others fighting with them across other parts of Morytania and that should they fail, others would always rise up to continue the fight. Upon the fate of the Myreque at the end of The Lord of Vampyrium, Veliaf disbands the Myreque, the values and hope that the imaginary Calsidiu stood for now gone.
