Huh...okay. I guess I'll have to work out some kinks in the CS. But how does a wyvern possess a human? Do I wear him like a meatsuit or do I dissipate and enter his body as an extra entity and constantly tussle over who has control over the body? And if I do go out of the human body to do whatever wyverns go out to do, won't the guy make a run for it and hide or alert others about the presence? Is it possible to possess a corpse?
