Sangahyando

Sangahyando (Q."Throng-cleaver") was the younger brother of Angamaite and the second son of Castamaite the Corsair (the grandson of Castamir the Usurper). A Corsair Lord, he was born in Umbar in T.A. 1555, but his family was originally from Pelargir, and his Dúnadan ways remained partially rooted in Gondorian culture. He and his brother were the two most powerful figures in Umbar's rich oligarchy, and they were both  exceptional Sea-captains. Sangahyando's exploits in the Bay of Belfalas and along the coasts to the south brought him great riches and enabled him to erect a huge castle (Barad Valasanga) on Umbar's Ship Island (Q. "Tol Cirya"). His keep dominated the northern quarters of the city, just as Angamaite's did in the southern districts.

In T.A. 1634, Sangahyando and Angamaite' launched their greatest raid. Gathering most of their allies' warships in the Nen Umbar, they sailed northward and struck the southern coasts of Gondor. They bottled up the Royal Fleet in Pelargir and slew King Minardil when he attempted to break through their blockade. Then, they ravaged the seaside areas of Belfalas, Lebennin, and Ithilien. Pelargir never fell and the Corsairs never reached the rich lands of Anorien, but  the damage they inflicted on the South Kingdom was considerable. Both Sangahyando and Angamaite returned home as heroes, having avenged the defeat suffered by the Corsairs' ancestors in T.A. 1448. Only two years later, however, a rival oligarch murdered Sangahyando. The exuberant Sea-Lord died of a knife wound inflicted by a Variag assassin in Umbar's great theater.
