Victory Wild Devil is a Brett L fermentation. Those earthy, leathery, musty, dry spicy notes are the signature of Lambicus. The Muse has a lot of similar things going on when you compare it with Wild Devil.
Brett is a lot like Sacc in most practical brewing applications. It does produce heat, but most Brett strains ferment slower at similar fermentation ranges. The Muse fermented with room ambient temp and the thermometer on the fermenter said it was only a few degrees over, so 72f and it took about 4-5 weeks and got about 89% attenuation.
My latest,
http://www.homebrewtalk.com/f127/bard-all-brett-b-brown-147712/ was fermented when room temp was a bit lower, about 65f and also took about 4-5 weeks before it was completely done but didn't finish as low, I think around 85% attenuation.
