Grotch:
“We didn’t plan on holding this post with this sir, we planned on summoning a warlord here that can help us make this a new thriving empire!”

Sclawous:
“A little suckup-ish dear boy, but else i loved it! Let us get cracking then!… I have a hard time understanding that last part of the “forge building” thing. What does it really do?”
