I'm planning on having Glacius put up a network post at some point offering to provide for those who might have a hard time doing it on their own since he is literally in his element on a wintery planet. This will involve a lot of exploring, hunting, and foraging, so:

1. Assuming the apex mammoths you mentioned will be his biggest threat creature-wise? I'm guessing monsters from the door post-jump will still lurk around the outskirts as well?
2. Are there any sort of edible plants to be found or will most of those still be in the gardens and orchards?
3. Assuming he hunts rigorously every few days, about how much will he reasonably come up with? He is the best of the best at what he does, but I don't want to end up with a situation similar to the old forest where he's providing more than is feasible within the world.
