I've experienced more disgusting animal traits than that. I'll cope. That's what baths are for. Thanks for the warning, though.
Religion, hmm. The main one is the Chantry. The idea is that the Maker created the world. First the Fade, the dream world, inhabited by spirits and demons, then later our world, inhabited by...well, life. But when mankind sought to go the to home of the Maker himself, the Golden City, he cursed the city and them and turned his back on them. Eventually the prophet Andraste tried to persuade him to return, and he agreed on the condition that everyone repent, renounce any false gods, and follow his commandments.
