Geryon Sybil

Geryon Sybil is the butler of the Welkinvaar, currently in the service of Kalen Lorwyan, the Fourth Warden of Silverfall. Sybil suffers from split personality syndrome, which presumably developed when the previous Warden, Cloudmaker (Aris) Benzel was killed. One of his personalities still server his old master, the new one, however, accepted Kalen as the new Warden and serves him well. His other self, of which he has no previous recollection, often tries to murder Kalen, which poses a threat to him, but instead of exiling Sybil, Kalen embraces his dementia and wishes to keep the butler in his service.

Personality
Geryon Sybil was also a welkinward before becoming Benzel's butler, he was regarded as one of the best swordsman of his time. During the war of the sands, he carried out his tasks remorselessly, but held no personal grudges against the Niskarim people. He regarded them as efficient soldiers.

Once, during the investigation of Beleriach's disappearance, when the Wardens start suspecting that Sicario or Niskaru is involved, and capture one of the 'Timeless', Niskarim assassins, he welcomes the thought that instead of the militia of Silverfall, Niskarim agents should do the torture and interrogation. When asked why he thinks that, he only responds: "They are more violent", possibly noting that the interrogation will yield more results in their hands.
