Ok, so you're frustrated with this game, and you're thinking, what, are these developer guys so artsy that they'll have a game end with so many knots untied (*cough* MGSV [thesnakesoup.org] *cough*) ? I mean, there's only so much you can leave up to interpretation, right?

Or maybe, unlike me, you're a normal person and you realized you really didn't beat the game.

Or maybe you don't care about spoilers and you've already seen the ending scenes on YouTube, and you're wondering, How come I couldn't get that?

SO!
Here's what ya gotta do:

Go talk to Allison back where she said she'd be (that's Fort Hope, in case you've forgotten). Then you also have to talk to her father, who is standing next to her...in the dark world (interesting, no?). You might also have to talk to Clement Wright in the Forbidden Woods...wait, no, that's LoZ:WW Wilds--he's not hard to find; he's the only spirit you can talk to there.

Then, once you finish James Markley's investigation, you can finish Allison's, and then you'll be able to go on one final quest through the whole map where you have to find all pieces of the TriForce release all the wraiths from The New World. (So, finally, you can do something about those inverted red triangles on the map that you could never clear).

If you need more help or explanation, just comment below. Happy hunting! ^_^
