*spoilers all books* Dragon Haven, Enjoy it? Hate it?

[joost]

I am compiling a list of dragons and keepers, but I seem to be missing a few connections. Perhaps someone else can fill in some blanks?

Dragon - Keeper
Arbuc - Alum
Baliper - Warken(+)
Fente - Tats
Heeby - Rapskal
Kalo - Greft(+)/Davvie
Mercor - Sylve
Ranculos - Harrikin
Relpda - Sedric
Sintara - Thymara
Spit - Carson
Veras - Jerd

I can't find the keeper for Sestican, and I can't find the dragon for Kase, Boxter, Nortel and Lecter. Can anyone fill in the blanks?
