Lassivern The Dark's Spear

The Spear of Lassivern the Dark. A monk of the Order of the Scarlet Brotherhood on the continent of GreyHawk. Lassivern was  a powerful monk whom did not dwell in the confines of a monastery. He ventured out to complete and fulfill the needs, desires and instructions of a higher power - unknown at this time. Completing many quests, both for evil and some good even, but always lawful the histories say. 
At one time the leader of the Order of the Scarlet Brotherhood for over 100 years, it is unknown except perhaps by sages and historians how he fell from power. He disappeared from history, and his powerful weapon the Spear was lost as well. 
It seems the weapon has resurfaced - used by the Black Duke to control the Rod of 3 Parts, and now to be used by one of the Heroes of the Laughing Moons........

The broad leaf-bladed weapon is close to 8 and a 1/2 feet in length. The head of the spear looks to be made of a mixture of adamantite and mithril. The Haft being of a unknown black metallic substance, a close look reveals what look to be stars and swirling galaxies. They seem to move....
