Oshu

The First Prime of the System Lord Yu. Loyal to his master even when he knows that Yu's judgment has been compromised by the ravages of old age and senility, Oshu often takes charge of Yu's armies when the Goa'uld needs rest within the rejuvinating sarcophagus. He is greatly concerned for the well-being of Lord Yu and his domain, and is eager to aid in the destruction of Yu's enemy Anubis. As witness to the slow deterioration of his master, Oshu is beginning to believe that even "gods" cannot live forever. He has, over time, watched Yu turn into an aged, narrow-minded and aimless leader.
