Sacred Haven of Debauchery

I put Alistair on the throne. He killed him.

I spared Loghain, the Queen declared me the future... forgot his title? King, basically, but she executed Alistair, arguing that he might later incite a rebellion in his name. :smile31:
I didn't object.
Spoiler:
After that, Loghain becomes a Grey Warden and travels with the main character (by the way, he was stronger than Alistair).

By the way, I found the Ranger too late to learn his skills.

What's there to find? I bought it from a merchant for 30 gold, and that's it.
