This is a nice series of loosely connected encounters. I really like that not all of the random encounters are combat encounters. I also really like how you align the minimal stat blocks to the margins right next to where they'll be used. Very convenient.
The number 4 encounter kind of bothers me, I don't like putting characters in situations that they have no control over, and especially then having dire repercussions like the loss of a limb, and although I do think the idea of a 33% chance of another character eating it is funny, that also robs that character of their agency.
The fishing hut encounter is pretty fun, but the repercussion for accepting the fish seems rather high, especially since there is a possible health benefit. It seems almost like an unnecessary amount of logistics. I might just have it be discretely poison, and then have the fisherman try to put them down the fishing hole as bait or something.
I really like the hansel and gretel vibes from Morkshire, also a funny name. This probably won't come as a surprise, but I think having a player die just for walking into a house seems excessive. At the very least, I'd let them save, or take damage - and then I'd probably also make sure they have the possibility of knowing there might be something dangerous behind that door.
The Wendigo though, man, this thing is cool. Everybody else has said it, but I love the idea of having players roll to determine the things ultimate HP. There's so much good stuff happening in this battle. Children in need of rescuing. Skeletons rising as weak minions. The imagery of this thing plucking stars from the heavens is just fucking epic.
The icy breeze seems kind of problematic though, I worry that having a player out of combat for 4 rounds would be really not fun. I know I would space out and likely stop paying attention to the game for awhile. It really depends on the DM how fast these combat rounds are going to go, so it might be fairly quick (but even minutes can feel like a long time), or excruciatingly long on the far end of the spectrum. I might limit this to d2 rounds, or make them choose between movement and attack or something for that time-frame, instead of being unable to do anything at all.
Overall, I think this would be a lot of fun to run, and that Wendigo battle is likely to be the stuff of legends.
