Heart of the Fallen Land Walkthrough
Once you entered Iz, Areelu will show up, telling you this is a trap set Deskari, and queen Galfrey is in danger. However, if you go save the queen, you will lose the chance to find Areelu’s old note and key. (the crystal can be found in a room on top, the glass key is in a hidden chamber near the entrance)
Other Pathfinder Wrath of the Righteous Guides:
If you go the the Temple of Stone Manuscript first, the queen will still survive, but Irabeth will be killed and you lose the opportunity to romance Galfrey. (If you gave the lexicon to the queen, she will use it to protect herself, and returned it to you afterwards.)
If Hulrun is alive and supportive, he will hold the camp and banner, even if you went to the library and queen first.
Be careful, the battle with deskari will completely change the map of Iz, make sure you have explored the whole area before facing it.
Farewell, Iz. Farewell, cleaver heart of Sarkoris. You have become the site of a great battle, of great meetings and partings.
