In classical Roman religion, a genius loci is the protective spirit of a place, and is often depicted in religious iconography as holding attributes such as a cornucopia,[Footnote 3] patera,[Footnote 4] or snake.
Demonreach's own genius loci is a figure eleven or twelve feet tall, with a billowing black cloak, a limp (caused by the glacier that carved out the lake), and two vividly green eyes. Within the island's boundaries, it shows Intellectus, and is able to resist the power of Maeve.
In the seriesEdit
In Cold Days, Demonreach guides Harry Dresden and Bob below the surface of the island, showing them where Dresden's body passed the previous year in one of its underground chambers. When Dresden and Bob to realize that the island is a huge prison for powerful magical creatures, such as a number of Naagloshii, dark gods and other nameless creatures, it informs them that Dresden is its warden.
