The whole point of Tyras special ability could have been better explained. We try to make it better with next rulebook edition (coming up soonish). Anyhow, to enable the ability, you need to be in Special spoke of the wheel.
Once it's enabled (or activated if you will), any movement type action (including the movement after special) is counted as Charge. And if you do NOT attack on those "charge" actions, the special ability is disabled (or turned off).
I hope this clears the situation, if doesn't, let me know and I'll try again.
And thanks for the compliments. Make us all happy. We worked hard to create different kind of dungeon crawl experience.
