The Trust healer in Windy is Kupipi she is in Windy Walls in Heavens Towers. I will put a link below that is pretty detailed. It covers several of the Trusts that you get in Windy and has references to different problems you may run into while trying to acquire them.
You see Windy has this HABIT that has always caused me to see red, start screaming unladylike words and start throwing things.....you can't just do 2 or 3 quests to get an objective do n e. Ohhhh nooooo, that would be too freaking easy. In Windy you are required to do quests that have 25 prequests where you end up traveling all over the freaking map just to complete a simple end uest (mumbling unladylike words under my breath). Sorry...I know I just went off on a ramble there but there are at least 5 NPCs that I've seriously tired to kill in Windy over the years.
