I'm searching for Gronda Patriarchs in my quest to make a pet with good, well rounded resists, but I haven't had much luck. I know they are on Corellia, and they do not appear to spawn out of Gronda or War Gronda mission lairs.

Any suggestions on where to look would be much appreciated.

I have found them almost everywhere on Cor. Never found them in actual missions, I always found them spawning with the random spawned nests.
