Audible glamer
From Ardrana
When the audible glamer spell is cast, the wizard causes a volume of illusionary sound to arise, at whatever distance he desires (within range), and seem to recede, approach, or remain at a fixed place as desired.
Note: This version of audible glamer originally appeared in the 2nd Edition Player's Handbook for Advanced Dungeons & Dragons from TSR. Its use here is for the purposes of providing context for the campaign only.
