( S.I.L, or Standard Interdimensional Language is a language used by those who travel the multiverse. It's anomalous in nature, as those who know of its existence can instantly understand it and speak it effortlessly with no prior knowledge. To those who can't speak it, it sounds like random babble. Several theories have popped up about what it was and where it came from, from it being the default language of the multiverse, to it being the language of the Elder Beings. It is largely a mystery about how and why it works.)
