Hi, I'm just wondering if it is possible to join House Indoril? It seems like it must be possible somehow, because there are quite a few Indoril traders (e.g. around Roa Dyr) that say they will only trade with members of the house.
I'm doing a playthrough currently, with an Argonian warrior, and I couldn't figure out how to join, despite talking with House Indoril people quite extensively in Akamora and in many of the Indoril settlements on the East Coast of the Aanthirin. I did the quest for the person in Roa Dyr that involves investigating a supposed Hlaalu plot in Vhul. I also did all of the Indoril bounty quests and spoke with Indoril Ilvi afterwards. However, after the bounties ran out, there was no option to join the house and I wasn't able to find any further opportunities to do work for them.
I am a member of the Fighter's Guild - perhaps that and being an Argonian might have something to do with it (incompatible race/faction)?
In general, it seems much more difficult to join Indoril than the three houses in the vanilla game, each of which pretty much allow you to walk in the door and sign up. For Indoril, I don't think I was even able to find a conversation topic anywhere about joining.
Btw, if it is possible, I'd appreciate if people could try not to post spoilers (although 1 or 2 hints would be nice!).
