How do you upgrade a village into a town?
First, have a village.
Hah.
Second, be a noble. Or be favored by a king.
If the latter, how lucky! Simply ask the king for a town charter.
If not in the favor of a king, like the very plebian Krow, hope that you have a good registration roll or go and quest for a castle.
If you want a castle, good luck! Hope you can survive a raid at your level (lol).
Third, have a ton of money.
Oh, too bad. He was broke.
Why, it's easy to fix that: slaughter is the only way!
So simple! Just carve a bloody path through million and a half monsters that spit acid into your eyes, bite through your clothes, and put you in a constant state of being minorly poisoned!
Krow sulked in his mental commentary as he waded through a mass of dead Tasseline Verdant Serpents.
[You've butchered a monster to acquire its Tasseline Verdant Snakeskin!]
