Eshka

Eshka the architect of the Tomb of Praecor Loth on Rhiannon.

The Avatar never met Eshka, as he'd lived centuries before the Avatar found Rhiannon. Instead his report of the last inspection of the finished tomb was found (as read in the Ultima Underworld II Clue Book), in which he gave a last report on all the traps and ways in the tomb. During that inspection he was annoyed by various cave-ins and didn't dare to approach Lethe, therefore not learning what happened to his king.

Eshka himself had no illusions about his own future. He knew he'd end up as a slave to the Guardian, either working in the mines or rowing a slave galley. He also knew that soon enough, his greatest work would become forgotten, as it should be.
