there are 3 main missions in alfheimr, one of them is the power hungry missions. to get/complete them you need to first finish all the previous conversations with the related captains.
for the fjord's mission, check if you didnt miss a conversation with jostein in britt's home or the stables, or anders's conversation in the artisan area.
for the undercity's, check if you didnt miss henrik's conversation in the apartments location in the core, or with ralf in the apartments location which is above the bar.
