This is the one that lets you put 3 heroes under it and protect them while in your territory. Can you also use it to put a Lost Soul in, like any other site? If so, would any site of any color "unlock" the site and give the rescuer access to the LS inside? Finally, can I do both---protect some heroes on turn 7 after my draw phase, but on turn 8, put Goshen atop a Lost Soul and leave the heroes in my territory? Then change again in a future turn?
