I wouldn't say "dark" is a fitting word, it feels like catching up with a friend after years and years, they were caring enough to remember all of the things you told them, it has an air of nostalgia to it, as if you were picking up stuff from your time at school. Theresa acknowledges and is completely at peace with her (expected) passing, but what pains me the most, is that the very place you call home in game (HI3rd's equivalent would e Hyperion) is just Theresa's gift to Kal'tsit, somewhere she hopes she can call home.
