PERSONALITY
Earnest is a deeply curious man, striving to expand is knowledge in every way he can. He likes to keep himself emotionally distant and professional, making his curious nature sometimes seem pushy and inconsiderate. While he likes to view everything logically, he has a faithful side that comes out whenever he feels conflicted on a subject or uncertain about the future.

VOICE
Earnest's voice is a medium pitch, "refined" masculine voice. He talks with certainty and calmness, speaking at a consistent pace without much emotional fluctuation. He does have a tendency to use sarcasm and act as if he's above others, so a good condescending voice is a must for Earnest.
Earnest voice reference isn't really a specific character or person, rather just the old 1940s-1960s generic male voice.

Earnest is from Finland, so a Finnish accent would be nice but is absolutely not required.
PRONUNCIATION
It was really hard to find any sources on either name, but I'm fairly certain Earnest is pronounced how you'd expect. This video features his last name a few times.
