Artifacts of Power and a Power Struggle

Short Version:

Still in Mordor, the party defeats a group of wargs to claim a grey stone of healing and a spiked warg collar. They also sift through the rubble of a once-great tower to find Sauron's mace and a necklace that allows access to any magical spell. After a heated debate, the group decides to destroy the mace and necklace, since they are evil. The group continues its winning streak to kill a great spider and claim both the Staff of Sorrow and the Golden Beetle. After yet more travelling and solving some riddles, the group is now very close to acquiring two more artifacts: some dice and a ring. However, it is yet to be seen whether the group can keep from fighting amongst themselves long enough to present a united front to any enemies they may encounter...
