So... I had an idea for Keris's eventual Excellency, and several Charms she could create for herself.
First Keris Excellency (hypothetical)
The Eternal Odyssey is the journey and the experiences so gained. She is whimsical and empathetic, quick to form bonds and slow to break them, and frequently accumulates responsibilities to those she meets in passing. She is a thief and a murderer, but seldom acts with malice.
This Charm may enhance any action the Infernal takes when acting without proper forethought. It may also enhance any action taken to evade the legal authorities, or to escape the scene of a crime. Finally, this Charm may enhance any roll the Infernal makes to flagrantly commit a non-violent crime in public, as long as she fully intends to escape the consequences.
However, this Charm may not be used to enhance any action that contravenes her Motivation, as the Eternal Odyssey is her own being first, and none may lay a claim upon her unless she allows it. This Charm may also not be used to enhance any action if the Infernal has channeled or successfully rolled Temperance earlier in the Scene.

Essence 1
Pre: First Keris Excellency
Permanent
Inconvenient failures and unexpected happenings are part and parcel of all creatures' journeys; hence, the Eternal Odyssey offers no guarantee of success. In place of a Second Excellency, Keris grants this useful Charm.
This Charm permanently augments its prerequisite, removing a restriction from it. The Infernal may now enhance her rolls as described in Keris's First Excellency, even during a scene in which she has channeled or successfully rolled Temperance. Additionally, the maximum number of dice the Infernal may add using Excellencies increases by 1.
The Infernal still may not contravene her Motivation using First Keris Excellency, as normal.

... and this is as far as I got before I lost motivation.
