+Artifacts
+.pg
+Some objects have been imbued with special powers and are known as
+\fBArtifacts\fP.
+They have specific types (such as long sword or orcish dagger) and distinct
+names such as \fIGiantslayer\fP or \fIGrimtooth\fP.
+Artifact weapons typically do more damage than their ordinary counterparts.
+Some do extra damage against all monsters, others only against specific
+types of monsters so aren't better than regular weapons against other types.
+Some confer defensive capabilities when wielded or have other powers that
+aren't listed here.
+.pg
+You might find them simply lying on the floor, including but not limited
+to inside shops, or be granted as a reward for \(lq#offer\(rq on an altar
+to your patron deity.
+A few might be dropped by monsters, or might be converted from an ordinary
+object of the same type via assigning the right name.
+.\" should we mention dipping for Excalibur here?
+Or you might wish for them, if you happen to be granted a wish, but such
+wishes can fail.
+.pg
+Some artifacts have a specific alignment, others don't.
+You won't obtain aligned ones that have a different alignment from yours
+via offering and might get a shock if you attempt to wish for any of those
+or find one and attempt to use it.
+.pg
+Each role has a distinct artifact that is contained in the \fIQuest\fP
+dungeon branch.
+These are commonly known as quest artifacts.
+All are aligned and most are non-weapons.
+They won't be found randomly.

+The \(oq\f(CR\\\fP\(cq and \(oq\f(CR\`a\fP\(cq commands will list

+Relics
+.pg
+There are three unique items that are named and have limited special

+Each is guarded by a particular monster and you'll need to collect all
