His face looked middle-aged with even, benign features. He wore his dark hair in a queue, hanging down between his shoulders, but otherwise unadorned. At his first appearance, he was dressed like a Malazan sailor in waterproof, faded leathers and a thin, ragged, linen shirt.
Banaschar sent a note to the commander of the Septarch City District guard of Kartool to inform them of trouble at the Grand Temple of D'rek.

Before Hellian could question him further, Banaschar disappeared.
Banaschar was now the last living High Priest of D'rek, the Mistress of Decay. His last title had been Demidrek Septarch of the Great Temple. In his life, he had travelled extensively, from Korel to Theft to Mare in the south; from Nathilog to Callows on Genabackis in the east; and, northward, from Falar to Aren to Yath Alban. 
Banaschar bankrolled the Bonehunters after their exile by Empress Laseen, as he had access to the Temple of D'rek's 'bottomless' coffers. He was attached to Adjunct Tavore's personal staff, under the pretence of a counsellor, however his constant drunken state hindered his role. Banaschar travelled with the Bonehunters into exile from the Malazan Empire to Letheras to tackle the Edur threat.
