Sources and review
Imagination opens the door. Facts deserve a look at where they come from. Here we bring the sources together and show what has been reviewed and what is still growing.
These sources support specific corrections, not a full certification of the game. When a specialist reviews a card, their name and the scope of their review will appear here only with their permission.

Language review
The cards exist in up to 8 languages, but not every Guardian has all eight. No translation is presented as reviewed by speakers of that language until we have that review documented.
When we correct a fact in Spanish, we remove the old version in the other languages so that we do not keep teaching the error. Until the matching translation arrives, those cards appear in Spanish.
Story and fact
The stories and many scenes on the cards are fiction: they open a question. The facts that go with them are the part we try to support with sources. If you find a mistake, write to us: correcting it is also a way of caring.
