[X] "You are my vassal, Yrael, but you are also my friend.
Grander, I spoke, if you remember it. And grander,
you said. Let destruction not be
our monument. I swear to you I will see this righted one day."
-[X] Explore Heaven
--[X] Look for clues as to the nature of the battle, the foes that stormed the gates. See what relics are left to collect for study to this end.
---[X] In the meantime ask Yrael and Mereth their accounts of what happened.
--[X] What happens to the dead souls who were bound for this place?
--[X] See if there are any survivors to speak to, or even their bodies that could potentially be brought back.
--[X] If there is anything to be salvaged still, it would be better put to use protecting the innocent than sitting here. See what can be salvaged among the ruins.
--[X] As a general note, stay away from the hole in reality, that doesn't look safe in the slightest.
-[X] Before poking around significantly, retrieve any Companions not currently busy. Malarys, Richard, Garin and Tyene at minimum.
--[X] In terms of preparations,
Attune Form and
Life Bubble should be enough to protect everyone present from any environmental effects.
