The Multiverse is so vast and diverse that all kinds of strange things might exist. Undead who believe in the Holy Light, kind-hearted devils, dwarves over three meters tall, drow yearning for the sun, and even ogres who don't eat humans...
But are there any herbivorous frost insects in this world? Perhaps there are, perhaps not. Even the wisest mage likely can't answer this question with certainty.
However, even the most difficult question might have someone who knows the answer. Oliver knows the answer to this question because he is the answer.
Yes, Oliver is a well-behaved, herbivorous frost insect.
When it hatched from an egg like a round snowball, it had never seen its parents. Of course, this is not unusual for frost insects as a species.
After female frost insects lay a pile of eggs as cold as ice, they leave on their own, not caring for their offspring's growth or survival. Newly hatched frost insects must take care of themselves during their most vulnerable period.
