When grouped for a port in Velious and lacking the proper dragon tooth key..
 

What message, if any, was displayed?

i.e.
Druid begins casting 'Circle of Great Divide'
You don't have Tooth of the Great Divide.
Spell resolves.

You are missing Tooth of the Great Divide. (?)

Wasn't it something about lacking the will?

IIRC, the message was "That zone is not available now."

The below seems like a good message.

"That zone is not available now"
You are missing Tooth of the Great Divide.

I believe it was:

"That zone is not available now"
