Ignatious' Sword

Intro
Ignatious' sword is a katana that was forged by his mother, but which seems to have gained some... additional qualities since Ignatious' near-death experience in some subterranean ruins.

Description
There are "shadowy markings" on the blade, which were not present before the events in the ruins.

The sword does not seem to cast a shadow - however, it appears in the hands of Ignatious' shadow when he dismisses it.

"New Tricks, New Troubles" (2x1)
When caught alone and unarmed by a plant monster in the forests near Wending, Ignatious discovered that he could summon his sword to his hand.

Twice in the aftermath of this battle, Ignatious heard distant weeping. He was unable to tell the gender or identity of the source, or its location, as it seemed to come from all around him.

"The Wending Way" (2x2)
Ignatious spent some time alone at the inn practising dismissing and resummoning his sword. After a few attempts, he heard "a very, very faint sound of laughter - and it sounds the tiniest bit hysterical." Ignatious then discovered that whenever he called or dismissed the blade, it seemed to be moving between his shadow's hand and his own.

"The Broken Sigil" (2x6)
When Ignatious dropped his Invisibility spell while following Yen'sal through the Sanctuary of Mayadine, he heard a sound "like someone far away is laughing very softly." The sound disappeared before he was able to properly focus on it, but he was able to ascertain that it did not sound like female laughter.
