The Valley of Locked Doors

There are many doors in Udûn, most of them locked tight. Reports indicate there might be powerful foes behind some of them.

Description
Stage 1

A notice is pinned to the board, stamped with the royal seal of Gondor:

'Our scouts have discovered many locked doors in the valley of Udûn. They have reported hearing Orkish-sounding creatures talking inside. An adventurer is needed to clear out the creatures hiding out inside these doors. Beware: Some of Ugrukhôr's lieutenants are still unaccounted for.'

Locked doors can be found in many places in the valley of Udûn.

You should attempt to open these doors and defeat whatever creatures lurk inside.
