The East gate of Osgiliath(e)

The great eastern gate of Osgiliath looms before you. The gates are foreboding, and the walls seem impenetrable. The black gates stand closed, the dreadful Eye of Sauron painted on them as a warning to all. Much has changed since the last human inhabitants of this city fled.
The forces of Mordor have gained a foothold in Osgiliath; you may find it difficult to win entry.
A dark brown haze covers the landscape.
The only obvious exit is east.
