Ancient Kalguuran text

I was going to start this Ancient Kalguuran text quest with the opened portals when my laptop crashed. When I came back online, the book and the portals are gone.

How can I find this quest logbook to give to Dannig and restart the quest?

Expedition logbooks can be obtained from expedition encounters, from runic monsters.

Them logbooks zones, once opened by Danning, can generate some side areas (at random) - indicated with special marker on your map. Once detonated/explored those areas will always contain ancient texts.

TIP: Remember to return discovered ancient text to Danning before exploring the other side area if your zone had more than one of them. By doing so, you are saving time and complete the quest faster.
