Dungeon
Along with Doom, the Dungeon of Fire is one of two places where you can find the Mark of Force. It's also one of three dungeons where you can find the Mark of Fire. Since you need both anyway, this is the quickest way to find them, though not necessarily the easiest.
This dungeon is long and desolate until you reach level 05, where things start getting a bit crazy. Here the path splits. You can avoid the traps and gremlins and stick to the inner ladder, which will eventually take you to the Mark of Fire and the treasure of Level 08. However, if you brave some of those traps and gremlins and head for the southwest ladder on level 05, you will instead find the Mark of Force. Because this is a relatively quick trip, I'd recommend doing it first if you aim to get both marks in one run.
