Don't worry about Kingmaker. No narrative connection
Apart from Tristian's single comment about the Worldwound and all the badness going on there, no? But otherwise - yes, it appears to be entirely separate.
Didn't even remember that shit lol. It happens in the same world, but no real connection other than some Easter eggs and cameos like this one. If you know the fire emblem series, it's like the connection between fire emblem 1 and 2
From yours and others, sounds like mostly just Easter eggs and slight mentions of it a la Dragon Age 2 referencing events in Dragon Age Origins but not being directly connected to it. Works for me!
If I like WotR I may eventually pick up Kingmaker, but admittedly first got interested in WotR for a specific companion I saw after looking it up (once I'd read through this thread when it was about... 14~15 pages long). However, I have a tendency to check out other games from a developer if I deeply enjoy the first I pick up from them (picked up Tyranny because I fell in love with Pillars of Eternity, for instance).
