She means to name the mightiest contract demon whose name she knows, one to whom other devils answer; the thought has occurred to Subirachs as well that Carissa Sevar is perhaps worth more than ordinary soul in their Lord's sight. It is not clear that Hell's profit should be protected at the expense of Sevar's dignity. On the other hand, if that thought hasn't occurred to Sevar herself, she may deserve no better. But she will at least bring forth a devil worthy of negotiation.
"Glosialabolas, come forth and bargain." So speaks the High Priestess of Asmodeus, Jacint Subirachs.
