I don't think that, properly used, imperial expansion and territorial expansion are the same thing. The root of emperor comes from Latin during the Roman empire.
The root of emperor - and imperial - comes from imperator or imperium. An imperator was a general who had won a decisive victory on the field of battle. Imperium was authority generals and governors (governors would of course be the highest military officials in their provinces) had, supreme administrative power. Both terms existed pre-Empire, during the Republic. Both words come from "imperare," to rule. The root of imperial has nothing to do with an empire except for the fact that an empire is ruled.
In fact, definitions of imperial which have nothing specifically to do with empires exist:
QUOTE (http://dictionary.reference.com/browse/imperial)
3. characterizing the rule or authority of a sovereign state over its dependencies
Stoll's expansion could be considered imperial in this case. But if you insist on an actual empire, there's more. Defining an empire is somewhat difficult, but I like wikipedia's general definition:
QUOTE (http://en.wikipedia.org/wiki/Empire)
Scholars debate about what exactly constitutes an Empire...Generally, they may define an empire as a state that extends dominion over areas and populations distinct culturally and ethnically from the culture/ethnicity at the center of power...The term generally implies military hegemonic power.
Going by this definition, a troll warlord conquering a gnome kingdom is building an empire. Thus, "imperial expansion" would fit the context. "
Empirical expansion," on the other hand, would need some additional explanation, though it's possible that Krunch's father is trying to expand his knowledge, or that Stoll is (edit: was

) involved in some crazy experiments.
It was probably a mistake. If it wasn't, we've got some backstory coming up. If it was, it's no big deal. I didn't even notice until it was pointed it out on these forums.
