I'll answer these as Grükhgr Truggsbane

1.) Two "trigrans" (guessing they're actually Tigrans) confront you in a dark alley and try to force feed you a strange green algae

[spoiler=This but twice][/spoiler]

2.) A grumpy dwarf that has one ear sells weapons in the sewer.

Probably buy weapons from them, if they're good quality? I don't see why having one ear, or being a Dwarf, has any impact on that.

3.) Rashaq. That's all I need to really say.

[spoiler=This but smaller]  [/spoiler]

4.) Racist Yanar with a broadsword 

Well, if they're being racist towards Orcs, you already know the gif.

5.) A man in a red vest gives you a purple flowers for no reason and leaves

Probably just drop them.
