He didn't know who found the way through or even how. He hadn't been there and with how insular his attention had been recently...frankly, he didn't care. What mattered was the word got out:
The doors were open, and they wouldn't stay that way for long.
Two days. Two days to get their affairs in order, pack their things, and then...he could feel it, that limitation on his power lifted, even if the doors closed, he could get them out of here once and for all.
He texts who he needs to, and arranges for what few goodbyes he wants to give, but to Jon and Amelia he sends one message:
Gather what's important and meet me outside of LIES.
We're going home.
He doesn't have much to arrange for himself; the Crucible and Interfaith Center no longer matter to him. He strips what altars he still has left and packs the trinkets and weapons that hold meaning to him in the largest yet easiest to carry bag he has. A few pairs of clothes go too, ones he likes, but not many. He should have clothes back home. He could buy the rest of them whatever they needed.
For leaving, his hands hover over the fancy clothes he'd arrived in the city in, the ones he'd once worn to the first meeting with Zenethil...he passes over them and takes only the thick cloak, choosing instead his usual outfit he'd taken to here. It suited him better these days.
When he's finished his last arrangements, murmured goodbyes to those he knew he had to let go, he waits for his family outside the massive building none of them had seen before. Or maybe, none of them had taken notice of before, some re-direction magic. Of course it had been hidden in plain sight...that was just like this place.
He wouldn't be sorry to see it gone.
