nice to see you again @Pauly7 .........too bad your not in Felyndral or I would snatch you up LOL......good luck in your hunts, I'm sure there will be plenty of people looking for a player like yourself :)
according to iDavis there is no quest to sell the Dwarven Portal......please check out their site here https://idavis-elvenar.com/index.html they list all the quests for all the chapters
I'm still a firm believer that no portal profits should be given out in the spire (especially in the purple chest) because we can craft them in the magic academy
I'm a little bummed (I do not believe this has been mentioned yet)......we no longer can build an ancient wonder that we plan on not keeping, then sell it so that the rune wheel is empty once again which allowed us to fill it back up with runes in hopes of getting shards to be used towards...
