If Sohothin was re-lit by Balthazar, how did that affect the curse of King Adelburn ( using Sohothin's twin Magdhar, sorry if misspelled.) Recall that Rytlock fell into The Mists using Sohothin in an attempt to break Adelburn's curse.
On a much more mundane level; If the Ghosts of Ascalon are freed from Adelburn's curse, it would mean that the Charr legions would not have that perpetual battle to counter them. The Charr would suddenly become much more powerful.
This could lead to Charr civil war, without the common cause to stabilize the triad of Legions. It could also unify The legions and refocus them on conquering everyone else.
That could easily lead to yet another Guild War and we wouldn't need to worry about The Elder Dragons... we might well destroy the world ourselves. Tyrian politics could very well be cast into chaos.
Here's hoping Queen Jenah is the leader she appears to be.
