Algarius takes the blade out of it's sheath. It's forged of what seems to be silver, and the blade shines almost supernaturally brightly in the sun. You give it a few practice swings, and it almost seems alive in your hands, directing itself towards your target (+1).

Before any of you decide to enter the Gate of Darkness again, be warned that Uthgur are one of the weakest of the Mirok, and if you stumble upon just about anything else down there, like a Galun, you won't last 10 seconds.

It exists on 8 layers: 4 Gates, and 4 Realms. All 8 planes are linked to some specific attribute of the ruler of it. Namely, there's the Gate and Realm of Darkness, Pain, Torment, and Destruction. The Gates are presided over by a Guardian. Should you manage to defeat it, then you'll be able to enter the corresponding Realm. After slaying the Ruler of the Realm, a portal to the next Gate in line will open. In some tomes, a ninth plane is implied, but nothing's really known about it. Any questions?
