Castle of Skull Lord

In a battle lost in the mists of time, the necromantic Skull Lord attacked and defeated the race of noble Dwarves. The Dwarves lost many treasures, the most valuable of these being the "Crown of Dwarves' Kings". For many ages did they attempt to regain this artefact and for many years did they fail.

Now in desperation they call upon you, noble warrior, to attempt that which is beyond their power.

Your quest: To regain the fabled crown and defeat the all-powerful Skull Lord.

The adventure is of the classic format. Simple verb-noun combinations are expected and will usually be understood.
