When Fragarach first came to this world, it
received immediate attention and quick
renown; so much so, in fact, that six other
swords like it were forged and enchanted.

These are lesser weapons, of course, and
their alignments vary. Each has a + 2 bonus
(and cannot hit opponents struck only by + 3 or better weapons). 
    <reading from the description of Fragarach, the implication seems to be that the bonus only applies to damage>
    <yet, it makes sense that the bonus does apply to hit creatures that are only affected by magickal weapons>

On a natural "to hit" roll of 1, no bonus applies;
on a natural 20, like their predecessor, the bonus is doubled (to + 4).

These lesser swords are identified by the differing gems set in guard and pommel.
They are reported to be
    * amethyst,
    * aquamarine  (),
    * garnet  (),
    * peridot,
    * topaz, and
    * tourmaline stones,
with combined value of about 24,000 gp per weapon,
16,000 gp per scabbard.

These weapons are named
    * Rebutter (amethyst),
    * Scather (aquamarine),
    * Replier (garnet),
    * Retorter (peridot),
    * Squelcher (topaz), and
    * Back-Talker (tourmaline),
in honor of Fragarach.
