Aaheru (pronounced AH-heh-roo) is a librarian in Yarma's House of Treasure. A devote priest of Thoth, Aaheru has set up a small shrine to his god in an out of the way corner of the library. Though born in Khapesh near the city of Dahshur, Aaheru journeyed south to Yarma in his middle age in an effort to spread his faith through the House of Treasure.
Aaheru is dedicated to ensuring all of the non-fiction works contained within the House of Treasure are factual in nature. He spend much of his time cross-referencing various books and pieces of writing, often performing his own research as well in unclear situations. Though he does not alter any books himself, quite a few works within the House contain loose pages with his meticulous notes and corrections.
