I tested by adding boolean variables MA and LA. EA was left out to avoid perfect multicollinearity, but statistically the model is still 100% correct since that is just assumed to be in the intercept (18.87 now).
Basically the base mage price goes up by about 9, but MA reduces it by about 9 too and LA by about 11. However, neither MA or LA variables are statistically significant even at 80% confidence level. The new intercept is valid at 80%, but not at 95% (and probably not at 90% either). Thus I can safely assume that era does not affect mage prices in general.
