So Suntiger has confirmed that we do indeed have a storage room that has one wall that's mostly window. He also says that we can convert it into a greenhouse by using a climate regulator, which can be made by using the same type golems used in the mimian plate armor.
I personally think that a greenhouse would serve our mission well, since part of our goal is to bring back items that could be of benefit to our clan. Any medicinal herbs, cooking spices, or even exotic flora for the beatification of Ama'varde could be stored until we bring them back to our capitol. Hel, we could study the plants while we travel. However, I should note that this room is not huge, so this *NOT* going to be some undertaking to build a massive shipboard arboretum or garden. This is merely to have a place to transport any interesting plant samples we might find or a supplement of herbs and spices.
Now to make this project work, we're going to need some people to work on the climate regulators and a few people to help grow the plants. I'm thinking that we could gather people together with the wood/plant affinity to help with the growing portion, since not only could we ensure our subjects/garden grows healthy and strong but we might also be able to accelerate growth for observation and testing purposes. I personally know my character has a wood affinity, but I don't know how many of the active characters do as well.
Of course if you don't have a wood affinity, you're free to help out as well. However I'm declaring right now that all ferals are banned from working with catnip.
We shall settle this in the ancient way. WITH A CHILDREN'S CARD GAME!
