Care to summarize for those without the book in front of them?
I run a homebrew setting where I invoke house rules, add races, add classes, and subtract both, too. There are politics happening that cause governments to rise, fall, become corrupted, etc. whether the PCs are involved or not. I very much hope the PCs will paint a big enough stripe across the landscape that I'll have no choice but to record their name in the permanent logs of my world. There is also a very real chance this campaign will be the last run in my world because the arc will alloy for the utter destruction of the cosmology if the PCs don't do something about it.
I presume that is 'tailored', but it might be 'other'.
