Not until the third last, "A Grove and Hideout". I don't yet have the Scouts Tavern. Seeds was less required compared to Mana and Unurium, but still needed for sentient goods of course, which is needed for settlement resources, and upgrading of buildings.
@Darielle You've reminded me I forgot to comment about my wonders, although you can see it in the city layout. I would definitely level up Temple of Spirits (mine is lvl 32) and Tree of Enlightenment (mine is lvl 31). I also benefitted from Blooming Trader Guild (31) and Vortex of Storage (31). To some degree Golden Abyss (33) as it meant I could afford to move all residences to Community Work, though probably more so from rushing it. I also have Sunset Towers (31) which helped with seeds and seed decay.
Because I removed manufactories to make space for the settlement, I also took a hit on Unurium production the Trader, which is worth being mindful of.
@Darielle that culture combination would be useful if you already have it. I had none, but still managed by ramping up culture by removing manufactories and using EEs, boosting the Community Work, gold and supplies. I used at least 182 Enscrolled Endowments to boost culture. If they lasted longer, and had a higher effect I would have benefitted, and also if I had a high lvl Dragon Abbey I would have then benefitted from that mana from that.
