If you look at the theme that she is playing Norfleet, it has easy access to Relief. Early in the game the Wyrm may have it's limitations (only being able to instagrab certain provinces alone, including water) but late game it is not affected by the common "encumberance" issue, simply because the nation's mages support it. The nation and the pretender can both teleport so there is no reason that when the Wyrm is running around, he doesn't have a chance of a Relief or two.
