Well, the Guild could go in the "secret society" direction and evolve from the resistance group along the lines that your Hero set forth in his/her path to power. As for the creatures of Albion as mentioned earlier, I see Hobbes as having no trouble making homes out of Albion's sewer systems. As for balverines, well, there's got to be farms for them to stalk somewhere, or hunt around logging camps.
Has the world ended already? Oh dear, I must have missed it. . .
