What the hell, have some Dorf:

Let's swim in the Sea of Racism!
rod- is a general locative, which in this context would be understood as "in". You could be a bit more specific with egrod- "inside, within".
As ever I can only take partial credit for the existence of Dorf. Words sourced from Dwarf Fortress language files are urmim, allas, arkim and lur.
