I had a good time reading this. There are two parts, regardless if your theory pans out, that interest me greatly.
1. Grimlock: I feel the sam way as you. They have this A list character for 5 years and havent done much with him. I forgot he was even around. I do hope he becomes the Grimlock we know and love again soon.
2. Tyrest, Pharma and Sabre: The wherabouts of those 3 is something I really want to know. They repesent the three pillars of society (law, medicine, and religion) gone wrong. I hope they come back soon, at least Sabre. There needs to be a rematch.
I still dont get what happened at the end of that story arc (with Tyrest on the moon). Here is the scene described in the wiki, if anyone wants to give me their understanding of it, I am all ears:
On the other side of the portal, a confusing sight greets Skids: a great city stands in the distance, and four moons float the sky above, as does a huge, multi-coloured spark. The orb of energy communicates with Skids in a synesthetic medley of sensations that he cannot comprehend, but his struggle for understanding is cut off by a cry for help from Rung from the other side of the portal.
