I am not so sure that first part is true as I thought Paisland was gifted to D'hara but I know the current lord went with.
Yes, Terran gifted Paisland to D'Hara, and the lord stayed in place, which I found quite aggravating as instead of waiting forever for both rulers to meet in the region, the dude could have just switched on his own. I had to wait a few days of pressure building up inside of me before he stepped down on his own and eventually rejoined Terran.
