A Lethrblaka is a creature from the Inheritance Cycle. A Lethrblaka is a parent and a mount for a Ra'zac.
It is pronounced leather blaka. This is a real word. It is from the inheritance cycle.
Oromis and Glaedr die. Those are the only major characters i can think of. (songjongsuk) there is also the ra'zac and the lethrblaka.
There are a lot of characters in Eragon. I will make a list of the main characters only as there are too many to write down.
