I've just taken a look through the tags that we use for the works of Rick Riordan. For those unfamiliar, there are different series, all of them dealing with mythological gods and monsters in the world today, all of them at least nominally set in the same universe.
Each of the different series at the moment has its own tag:
Also, we have a rick-riordan tag, but since we only use author tags for questions about the author...6
These are all set in the same universe3. I'd like a way to keep track of all new questions about this universe, without watching 6 different tags for the same universe - for now, I can search for questions with any of those tags, but it's... slightly clunky. How should we tag this universe as a whole?
1This is also being used as a sort of general universe tag for the Greek storyline - it's been seen on Percy Jackson & the Olympians questions, The Heroes of Olympus questions, and The Trials of Apollo questions.
2(Why don't we have the 'the' here? Ugh...)
3While The Kane Chronicles is a little less firmly set in the same universe, it's got enough clues and some shared characters that it's in the same universe... plus 3 crossover stories ;)
4magnus-chase-and-the-gods-of-asgard fits in the tag character limit, surely that's a better name that can be used...
5Okay, there's only one question tagged with this and I created the tag today. I plead guilty.
6Not that we have such a great track record of keeping with that policy...
