The Glittering Tower near the city of Lothern on the High Elven island-continent of Ulthuan.
The Glittering Tower is a fortified lighthouse south of the High Elven city of Lothern on Ulthuan.[1a]
Nearly a mile away from the Emerald Gate of Lothern stands the Glittering Tower -- a great lighthouse filled with thousands of lamps, situated on a rocky isle in the mouth of the treacherous Straits of Lothern. Mighty fortresses cluster at its base, each bastion made of marble, equipped with scores of bolt throwers and garrisoned by hundreds of Lothern Sea Guard warriors.[2a]
Designed to protect the Emerald Gate of Lothern, the fortifications blend seamlessly with the cliffs and rocks of the island, in a manner both lethal and aesthetically pleasing.[2a]
Anyone approaching the Emerald Gate can easily be caught in a crossfire between the massive war engines in the Glittering Tower and those on the gate itself. The sight of these imposing bastions is enough to turn all but the most insane attackers away.[1a]
