I'd be up to a thread. I offer either one of my Trenopians, that is Plerona or Orion. I think Kruz'Iik would have respect for either of them since they're both from a race of highly psionic people. A couple ideas as follows:
Plerona:
Perhaps Plerona finds a downtrodden, despairing family that has lost everything (or perhaps it's just one person) and she helps to counsel them, to bring back hope and meaning into their lives. Kruz'Iik could come into the picture then as maybe he's the reason for the family or person's grief and so the two meet on tense terms. Or he interferes somehow. It's just an idea starter and not a full one as I can't think of anything else right now. I'm hoping you can add to this.
Orion:
Both Orion and Kruz'Iik come upon a powerful object that they are both interested in for different reasons. Perhaps they discover it around the same time as each other. Anyway, Orion could want to find out as much as he can about it, and perhaps take it back to his home planet for safekeeping and further study, while Kruz'Iik tries to stop him as he wants it for himself? The nature of the object is yet to be determined. Feel free to add to this idea starter as well.
Or if none of those will work, feel free to suggest other character combinations with any of mine paired up with any of yours (except for Turquoise unless it takes place in the Open RP board).
