Hi!
I tried with a 4th character to finish the main quest - and to my surprise it did not work out - before the final part like i remember it i activiated the light of Meridia - and got telported back to the Temple in the lost City, Merida telling me that many died. The last king dies like when it finishes normally - but all are still in the harborage - and no Silver is here to start.
What to do now? - mission is not active anymore, so cannot restart it.
