Ahbhaer Mhilshoun

Ahbhaer Mhilshoun was a Calishite human inhabitant of Beliard around 1368 DR, who owned Milshoun's Stronghouses. He was a failed merchant but liked to give the impression that he was powerful with many connections in Calimport and Waterdeep, and was exiled as a satrap or magically powerful being.

Possessions
Ahbhaer possessed a spellbattle ring and a ring of magic missiles which had 24 charges.

Background
Originally from Calimshan, Ahbhaer gained his magical items by killing a sleeping wizard and stealing them.

Discrepancy
Although the establishment is named "Milshoun's Warehouses", the owner is given as "Ahbhaer Mhilshoun", which is a different spelling. Both are on p.37 of Volo's Guide to the North.
