Agarta the Devourer of Dragons is responsible for removing the darkness (serpentine dragons) that enter into peoples minds & corrupts their consciousness, but in order to do so she must first sacrifice her own memories. For her services she is compensated by receiving memories from long ago. Her only companion is a robot named 3-5-10 who assists her with her work & maintains her ship as well as being a sort of storage for keeping her memories intact and organized.
