WHAT DOES KEYLETH KNOW ABOUT KIMA. WHAT DOES SHE KNOOOOWW WHAT WAS THAT FUCKING WHISPER GOD DAMMIT
She doesn’t know anything particular about Kima, she’s just iffy on following someone who has already lost all of her companions to this quest deeper into this underground mess and into significant danger because that someone’s special friend said so in a dream.
Or, shorter: Keyleth is not big on the conventional gods and organized religion thing. She grew up in the wilds where the only superhuman forces were the forces of nature.
