Where to store high quantities of text?

I’m trying to make a quest system. And I do not know where I must store a large amount of text. This text should have the ability to not complex transfer to the user interface, as well as the ability to make localization for it. If I understand correctly, then text arrays can be quickly and easily used to transfer data to the user interface, but localization for such an array will not be possible. What are the options to perform the above task?

you can use Localization Dashboard from windows menu, it help you

I use String Table asset. Not sure if that had localization options, though.
