Nah, that's the Darksign. NPC hollows have it, as well. It also appears in DS2, also on NPCs. The Dark Sigil in DS3 also looks very similar to this and it explains that humanity is drawn into it, to be lost. Which we know as "hollowing". That's quite the contrary to a firekeeper, who amasses humanity. The firekeeper souls look like what is described.
