Okay, so I've just noticed this. Apparently, the thread assumes that Kilkil has Dragon Wings and Improved Dragon Wings from RotD. However, he demonstartes the capability of prolonged flight repeatedly which is only possible if 1.) he has the single highest CON score in the whole Stickverse or 2.) he has 12 HD or more. Given the effect of the Holy Word on him, on the other hand, he can't have more than 10 and therefore, by RAW, this explanation is highly improbable at best.
How do we know he doesn't have the Winged templateSS instead?
Here's another flight-related issue. It might just be that I wasn't here yet when this was figured out, but how exactly would STR 14 explain Celia carrying Roy? For a Medium creature with this score, a light load is 58 lb. or less and a flying creature can only carry a light load while using its flight speed. She could have Reinforced Wings and Heavyweight WingsRotD and pull it off if a fully clothed Roy weighs less than 175 lb., but taking the latter feat requires a STR score of 15.
