Heinrich Stürmer and His Companions

This person was encountered by Narcissa in the Brillig Brillig Zwerghof. He was dressed as a dwarf and had a long beard and a hump. However, Narcissa noticed that he was not really proportioned as a dwarf. He kept his face mostly hidden.
He inquired about Sigisar and kept asking what he was like. He also suggested that the monastic fighting orders Sigisar contemplated joining were not for him, among other things, because they held very prejudiced ideas about dwarfs, that Sigisar himself didn't share. He later invited Sigisar for an outing, where he told him that he belongs to a secret group called the Knights of the Tomb, who are keepers of the Holy Grail. He invited Sigisar to join the order in order to look for a lost comrade, Ingrid, and perhaps, to return the Grail itself from its hidden realm back into the world.
Narcissa attempted to entice the man to follow her to the citadel and meet with Sigisar there, but he insisted on meeting him at the Zwerghof, and resisted Narcissa's magical enticements to follow her.
The man did not initially give his name, but Narcissa suspects he was actually the same H that had Regin and Schweir deliver a letter to Sigisar at the citadel on his behalf. After meeting Sigisar, he introduced himself as Heinrich Stürmer.
Heinrich and his two companions followed Sigisar's companions to Schloss Hirschenwald, seeking especially to make contact with Edmon. They then said that they would do their best to keep Winifred and her companions safe. At this time, Heinrich's two companions were named as Leopold and Johann.
