Assuming you are using RMXP, there is one error on line 175-176, you need to replace...
# self.contents.font.name = $defaultfonttype
# self.contents.font.size = $defaultfontsize
self.contents.font.name = Font.default_name
self.contents.font.size = Font.default_size
then it seems to work fine.
for each of the properties (i.e. CHAR_AGE, etc...), you have an array for all of your actors. (starting at line 62)
CHARA_AGE = [<actor 1 age>, <actor 2 age>, etc..]
So if their ages are, respectively 18, 22, 65, ....
CHARA_AGE = ["18","22","65"]
The rest of the properties work the same.
The descriptions start at line 98. Simply replace
L1 = "Insert first line of description here"
with
L1 = "Brew is typically a lover, not a fighter. But when provoked, can be deadly."
