Kettest is rather outgoing and keen to do new things, though he doesn't particularly care to explore above-ground. While he normally wouldn't like leaving his hoard behind, he doesn't particularly have to - Hasandre has set all of his favorite gems into various bits of jewelry, which Kettest wears everywhere. This means that Kettest has a tendency to jingle and clink with every move he makes.

In some regards, it's a good thing that Kettest wears his hoard around with him at all times, as he can be rather careless and forgetful. He can set something down, wander off, and never remember where he set that thing down again. Among the rest of the gem dragons, it's almost legendary how forgetful Kettest can be.
