Over the centuries, the clan has bred and hybridized various sorts of fungus, splicing one with the other to produce species unknown to mortals. Some of these monster mushrooms tower as high as small trees... these gardens often become expansive jungles of weird, phospherescent beauty: slime moulds, enormous moths and the like ooze and whirr through the depths, just as birds and beasts traverse the terrestrial jungle.
