I'll start.
After we purchased the sixth page of her book on Rowl, she gave us some information on him.
She said that his strength is partially dependent on the amount of exiles that have currently contracted lyfelidaeism. The more lyfed, the more powerful he is, both in his physical and what some might describe as magical powers.
His magic powers include the ability to summon other lyfelidae at will, and to give lyfelidaeism to exiles who are injured. Currently, he can only lyfe those who are "red" and low "yellow." This may change as more exiles are cured or get lyfed.
Feel free to post about any contact you have with Rowl or Alice, too.
