DELTREE'S PROFILE

We never saw Taru grown up, but it's implied he's off-screen at at least one point. And I think Tehgonan's middle name is spoilered as a joke, as his mother uses it as a threat in exactly one scene.

Rehm's pre-game story is simpler than that. He wasn't imprisoned so much as enslaved. Like Dehl, he tried to serve the human world, but as soon as he showed a moment of weakness, they took advantage of him. Of course, he was so despondent by this point anyway that he didn't try to fight back. The ship mission ties in because he had originally been hired to scout it after escaping from his captors, but he got scared and backed out. Then, when Dehl's guild was hired instead, he confronted them afterwards. His own confrontation with Asarik (junior) was just there to show he had been mostly forgotten, and was technically free already. He still had the teeth to try to get revenge, however, even though it was against the wrong guy (as the previous high officer who ordered his detainment was dead/retired by this point).

Like I said, it's been a few years.

The thing about Dehl is, he is pretty broken, and almost selfish. He does all of these good things because, in his mind, it's making up for all the death/chaos that the Blue Plague brought. Bringing down the final boss is just another continuation of this. His final scene with Xopi is sort of a purging of himself and his past, for whatever good that would do for him.

Part 2:

I'm not sure who told - maybe it was me in one of my posts - but I am intending Marie to be among the playable characters for the finale. Since the cycle never reset, the planet is safe for now, but time will jump a few hundred years forward before she arrives, so it will be an almost modernized setting. And, yes, I'm planning for Daszk to be there, too. Someone's got to be the muscle, after all.

The final emitter's location is not important yet, but it will be eventually. There are one, maybe two lines of dialog in TR that hint at it, but nothing substantial yet.

The Tatzylvurm started out as a running joke sort of boss, and we haven't seen the last of him.

We haven't seen the last of The Black One either. And his cryptic threats are far more important than some science experiment. Moke is still just Moke, but there is at least one obvious connection. Tez's resonating with the magic/energy is not incidental, either.

Ros' story is, fan fiction notwithstanding, essentially done. Since he/she has so many potential appearances/personalities, it would be kind of difficult to carry that into a whole separate game.

The last hunter is in the Wadassia hunting grounds, all the way to the east. He's hiding behind some dead tree branches.

Yeah, I didn't have the time/energy to give a sidequest to everybody. Typically the ones that do not either get a star upgrade as part of their normal training, or from a storyline event.

Since Xopi is presumed orphaned in the ending sequence, it's safe to say Mahk didn't make it. He was pretty old by that time anyway. Tez probably doesn't know himself yet, since he's been pretty much focused on re-establishing communication first and foremost.

It's ambiguous! For all we know, they could have been sheltering him just long enough to kidnap him later. Xopi wouldn't know any better, so he would just see the "protective" side of things.

The Eros folk didn't define any emotional parameters as such; the Watchers took it upon themselves to do that instead, since they saw themselves as on a sort of "mission from the gods." For what we know, if they were told the goal was finding those who had "mastery over the power," that could really mean anything to them. Really, both games are so thematically different that the connection is basically just for completeness' sake anyway.
