The name Keighvin Silverhair is from a series of books by Mercedes Lackey
(& others) called the SERRAted Edge.
Ace's mother is named for an elf,
and when she had an entire litter of mackerel tabbies
(which Elektra refers to as "racing stripes"),
all the kittens were named for characters from the SERRAted Edge,
who are elves racing cars.
Keighvin Silverhair is the head of the elfhame Fairhaven,
and a powerful warrior and mage.
The nickname Ace comes from his white blaze,
whose shape is reminescent of the Ace of Spades.
