For the Death Gods like Hades/Pluto, Baron Ghede etc., there was also the "Dark King" Mentor Spirit in SR4, which sadly was not yet included in SR5. The Mentor Spirit provided Boni for Assensing and Spirits of Man, emphasizing the "Knowing the Names of Death" aspect. On the Downside, get -1 Die to resist Physical damage for beeing so close to the underworld.
Used it once for a crippled-then-augmented Ex-Military Mage with PTSD, who "found" his Mentor Spirit after the traumatic Death of his Squad. He also used his fallen friends´ Dogtags as a Summoning Fokus for Spirits of Man, and his Spirits would also look like them - a litttle bit like The Sorrow from MGS3. Pretty grimdark, but also pretty cool
