Now that I am not inebriated, I embarked properly. With the reagant names fixed, the only error I'm getting is the Impoverished Word Selector one, which is fine.
So far the fort is going well, and by well, I mean "hilarious". I embarked on half Terrifying Shrubland, half Mirthful Ocean. Mermaids swim by occasionally and laugh at the poor ponies being harassed by zombies and covered in the pony blood that rains from the sky. Three of the starting seven died to the zombies and the military pony I brought along apparently pissed off the zombie mafia and had all her kneecaps broken for her troubles. She has survived, however, and is now the fort's Legendary Crutch Walker. Migrants have all made it inside without casualties except one pony's pet rabbit (His other pet, a cat, was saved). Since the surface was forbidden for the longest time, we had nowhere to farm, and there's a multi-zlevel aquifer on the map, which made things interesting. Happily it turned out to be patchy and I managed a series of staircases past the water without needing any complicated breaching procedures. It also provides a clean source of well water, which was good for our injured swordspony founder, as she was stuck in bed for a season as the medical pony patched her up. Because we couldn't farm, foodstocks got dangerously low - as in, 4 edible plants total low - until I managed to secure a fishing spot. We then lived off seafood until we secured a surface bit for farming too. Then I remembered that apple-bucking produces essentially free food and felt stupid, but the ponies are enjoying their squid roasts, so whatevs.
Also, you might want to look into creating several more plant fiber fabrics that are more common, like cotton or farmable/hiveable silkworms or something, because the only cloth my civ has access to is apparently silk roses. This created a hilarious situation at embark where the silk rose cloth/thread/ropes that were automatically queued ate up all my embark points, but promptly gave me over 1000 points back when I eliminated them, which is kind of exploity and not intended. (It did allow me to bring a steel weapon and armor for the swordspony, though, which saved her life, so I was rather glad for it, but you probably don't want 1000 points of free stuff just for not bringing cloth.) Cotton/silkworms with a larger biome range and that are fairly cheap should solve this.
