Darkness Falls on Sevinpold (2002)

From sevinpold.com:

There is only one way to save Sevinpold...
Unite your team of Valiants against the power of the Darkness in a fierce battle to save Sevinpold from eternal night. Proclaim victory only when you return The Scepter to The Living Throne. But be forewarned: The Darkness grows stronger and more menacing with every bolt of Dark Lightning.

You will not know who triumphs until the last roll of the dice.

One player is the Darkness, each other player is a Valiant - all the Valiant players work as a team. The square-gridded board is filled with castles, each containing a treasure. Some treasures allow the Darkness player to add another piece, some provide benefits to the finder, and two are required for the Valiants to win - the Scepter must be brought to the location of the Living Throne.

On a turn, a player rolls 2 dice and can move using either one, the total, or the difference. Moves are in a straight line unless both dice are used, when each can be used in a different direction.
