31) Is there any confirmation regarding the relationship between King Berthold of the Troll Kingdom and the Great Dragon Kaltenstein? Further, does anyone have any insight as to the reason why Lofwyr and Nebelherr fought Kaltenstein to prevent him from rescuing Feuerschwinge? The accounts are vague on the why...
This is pure speculation on my part.
Odds are Nebelherr got a good look at the SOX earlier and knew it was a toxic zone and would kill or at least corrupt any dual natured being, counting dragons. Once Feuerschwinge got shot down, Nebelherr probably knew that Kaltenstein would try to save her. I believe that Harlequin hints that Kaltenstein and Feuerschwinge were mated in
Dragons of the Sixth World, but I could be wrong about that. Anyway, Nebelherr didn't want a great toxic dragon, so attempted to stop Kaltenstein from entering the SOX and probably just assumed Feuerschwinge was dead or that the mana warp inside the SOX would finish her off. Nebelherr being only an adult couldn't possibly stop Kaltenstein himself, so called in a favor to Lofwyr to help stop old Cold Stone.
