I started by securing the camp's perimeter. This begins with the nearby Fade rift. I closed that, then found the Fade-Touched Lurker. I think this both secures the camp and introduces the party to the tough new enemies of the region.
After this head north, and I think the next thing I did was establish the camp near the cave. Then I went through the cave and found the Inquisition soldiers who were being attacked. This introduced the party to the Jaws of Hakkon.
I then went forward with the plan to clear out the riverbanks to secure safety of the soldiers. Closes some more rifts. Then while exploring the river I came to the glyphs and ruins, but passed on those for the time being to establish better camps in the trees. Then I found the note about Grandin and the other guy.
After that I returned to Harding and heard about Grandin going missing. So I tracked down Grandin, and killed him. I passed by spirit girl on the way and talked to her about her exile.
Walking back I noticed the Orlesian animal researcher and did his quest with the traps and wards. Again, protecting Inquisition troops from wild animals. Then I set out along the coast. Passed on the giant for the time being, then talked to the fisherman. I then established the camp north of that, closed the two nearby rifts, and then set out into the bog. I saved the elf women, killed the lurker, killed some Hakkonites, then set the bait for the white bogfisher. Killed that. Then I went around collecting the blood magic bones and saved those for later. Went back to the Orlesian and finished that quest.
Then I think I explored the ruins near the frozen wall, closed the rift, fought Hakkonites, and then I think I went to Stonebear Hold from the cliff side entrance. Did stuff there. Helped Finn since I already killed the FT-Lurker. Talked to the Auger about the bones and what-have-you. pwn'd the tournament. Then I think I saved Stovacha at this point. Went back to the fisherman, noticed a woman on the dock. Talked to her about her sister. Went back to the bog and cliff to track her down. Did that. Did not ask her to include me in her prayer. Went back to the sister on the dock. Then I think I looked for clues about the exile and did that side quest. Encouraged her to part with the spirit.
Then I think I went to the island after this. Did all that. Got the bubble shield. Killed the Hakkonites there.
Then I think I killed the giant after this.
From here, it was game time for real. I did the thing with the temples and cleared out the Hakkonites and their champion.
Then I think I made sure everything was completed, such as the Forgotten One's tomb with the shard door.
Then blasted the ice wall, got the Avvar in action, stormed the temple, took down Gurd Haroffson Revenant, then I went out to collect the memories, then back to camp to talk to Harding and the historian guy, revealed Ameridan was an elven mage, (I told Ameridan the truth about his wife also), then I went out to regain Sera's focus, and then took down Hakkon. The end.
I did everything. If I forgot to mention something, I apologize. Obviously I made claims and found shards and solved Astrariums along the way.
