I recently downloaded and installed Tamriel Rebuilt 1 & 2. I decided to check out the Firewatch area. Everything looks nice and the castle is huge. There is a Mages Guild here so I go to check them out. Unfortunately everyone in the Mainland Mages Guild knows I'm a vampire so I can't travel or buy from them even though I beat down Trebonius for head spot on the island. I haven't run into the Telvanni yet but I think they might be the same way. Is there a patch or any tweaks I can do (hopefully not too technical) to fix this? Thanks in advance.

Well, the mainland Telvanni are a different faction from the Vvardenfell Telvanni. I've never been bitten or become a vampire before, so I don't know how gameplay is affected, but if you can't join guilds as a vampire, then you'll have to get a cure first in order to join. Unless you want to join via the console.

I just made a small patch for that today, in fact. I could mail it to you if you PM me your email address. If you'd like to reproduce the patch yourself, it's pretty easy:

You just need to change 2 of the Persuasion/Service Refusal dialog lines that start "I will speak to you, vampire, but will not serve you."
To each of these dialogs, add the filter for a "global" comparison >= 2 for the variable named "emb_option_npchate"

Save your new plugin, add it to your load order and you should be able to be served by TR Telvanni and Mages Guild.

That sounds simple enough. Do I load all the TR's + VE & VH base? Thanks john. You're always saving my game. I doubt my character would have gotten this far into the game without your help.

The crucial one is TR_Map1.esm, because the 2 lines of dialog you need to add that filter to are in that plugin. I would also load Vampire_Embrace.esp as it defines the global and I guess the 3 Bethesda masters.
